FactSage dongle status
- When a valid FactSage dongle is attached to a USB port on the computer you are able to run a standalone version
of FactSage.
If FactSage issues an error message about a 'missing or invalid FactSage security key'
it goes into the FactSage SetUp mode with a green screen.
There are several factors that can cause this to happen.
The 'FactSage dongle status' Window shown here is for an installation where a valid FactSage dongle
is attached and everything is in order (i.e. 1 - 5. All OK).
The FactSage 8.4 Installation program enables you to update/refresh FactSage 8.4 software,
documentation and databases to the full FactSage 8.4 package.
You can upgrade FactSage 8.0 - 8.3 to FactSage 8.4 but
you must not upgrade any FactSage 7.0 - 7.3
currently installed on your computer.
You can update/refresh a FactSage Standalone computer or a Network
Server. In the case of a network installation it is
only necessary to update/refresh the Network Server.
If your computer has access to the Internet you can use FactSage 8.4 to download and update various
FactSage files from www.factsage.com.
Information on updates ...

This was first introduced in FactSage 8.3 and it works well.
With the FactSage Add-ons menu it is possible to run multiple instances
(i.e. copies of the software) of Equilib.
That is, it is possible to have separate copies of Equilib running simultaneously but independently from each other.
For more details refer to
Add-ons, apps and shortcuts in FactSage 8.4 .
This new feature in FactSage 8.4 enables you to select and define the composition of an industrial grade alloy of
aluminum, copper, magnesium, etc.
Details are given in the Equilib - Advanced Features Slide Show in the new section 16
Selection of an Industrial Grade Alloy (pdf file)
In the Equilib Reactants Window click 'Edit > Select an Alloy Grade ...'
to display the Alloy Grades Window.
Then select the alloy, for example Copper alloys, then the grade (brass, bronze , casting ...) and finally define the composition.
When defining the composition of the alloy a Help panel is posted.
For example, in the aluminum 2024 grade alloy above the wt.% Mn 5 is highlighted
because the composition is outsde the recommended range 0.3 - 0.8 wt.% Mn.
When editing is finished you must decide if you want this composition grade to be saved as a "mixture"
(*.mixt file) which can then be imported in the "Reactants Window" at any time.
If the compostion is not saved as a "mixture" it will be simply imported into the "Reactants Window"
as the reactants listed here.
Also you must decide if you wish to include 0 wt% elements (Cr, Si, Ti, Zn) in the list of element compositions.
When ready click on "OK" to save the system or click "Cancel" to quit.
When done you will returned to the Reactants Window.

What's New in Macro Processing
has been updated and gives a summary of the more important programming changes in
Macro Processing that have appeared since FactSage 6.1 (2009)
until now FactSage 8.4 (2025).
In FactSage 8.4 a new Macro Editor is available.
The editor includes the traditional File (Open, Open recent, Save, Save as, etc.)
and Edit (Undo, Copy, Paste, Fine, Find next, etc.) drop down menus.
With the Macro Editor the macro commands, functions and varibles are displayed in a variety of colors selected by the user.
This much improves the readability of the macro and interpretation of the program flow.
In addition there is the option to Run Macro without having to exit the editor.
Frr more details consult the
- Macro Editor Slide Show.
This was first introduced in FactSage 8.3 and works well.
With the FactSage Add-ons menu it is possible to run multiple instances
(i.e. copies of the software) of Phase Diagram.
That is, it is possible to have separate copies of Phase Diagram running simultaneously but independently from each other.
For more details refer to
Add-ons, apps and shortcuts in FactSage 8.4 .
In FactSage 8.3 two OptiSage Apps were released - the traditional module that was developed in the early 2000's, and a new module that had been completely re-written.
This new app was named Calphad Optimizer.
For latest news on the improvements and enhancements visit
Calphad Optimizer What's new?.
Note:
The Calphad Optimizer is not included with the standard FactSage installation because
there are regular updates to the OptiSage package .
It is necessary to download the package from the Internet.
Add-ons Menu
Add-ons are not part the regular FactSage package but rather are additional Apps that are offered for free to users who have current Maintenance and Service, M&S.
Access to the Add-ons is only available while the M&S is valid.
That is, access to the Add-ons will not be available when the M&S has expired, although a grace period of a few months may be added.
- in the FactSage 8.4 Main Menu Window click 'Add-ons > FactFlow process simulation ...'
Traditionally, these stream-related tasks were sequentially performed in the Equilib module often employing macro processing.
This is time-consuming and difficult to automate.
For these reasons, we implemented the powerful graphical interface called FactFlow which allows one to fully exploit the FactSage databases.
For detailed information refer to
The screenshots below illustrate four pyrometallurgical processes which have been built using the FactFlow interface.
For more information please contact Prof. J.P. Harvey (j-p.harvey@polymtl.ca)
or email the FactFlow team at factflow@polymtl.ca
- in the FactSage 8.4 Main Menu Window click 'Add-ons > FactProSim process simulation ...'
FactProSim, a new platform for process simulation provided with FactSage 8.4, is designed to assist the development of process
simulations based on the local equilibrium concept using the Effective Equilibrium Reaction Zone (EERZ) model.
FactProSim uses an intuitive flowsheet diagram approach to model the process with modules, which interact with
each other through the flow of materials. It is designed with a drag-and-drop approach, providing a user-friendly
interface with no coding required. FactProSim has four simple modules to create the process flowsheet of any complex reactor.
FactProSim offers the possibility to enter various inputs in the flowsheet modules (such as material composition,
amount and temperature, equilibrium calculation conditions, etc.) through spreadsheets by linking one or several
Microsoft Excel spreadsheets to a flowsheet. Furthermore, the output of the simulation is also saved in Microsoft
Excel spreadsheets to provide a convenient way to analyze and represent the output data.
Several flowsheet examples can be found in the folder \FactProSim\Projects.
Both FactFlow and FactProSim packages have access to the suite of FactSage databases.
For many years we wanted to develop a process simulation package that would provide a powerful interactive
graphical interface to replace Equilib and macro processing.
Two groups, one at the
CRCT, Montreal, Canada
and the other at the
High Temperature Thermochemistry Laboratory - Seoul National University, Korea
were eager to take on the challenge.
It would have been ideal if they could work together, but the huge difference in location and time between the
two groups, as well as a difference in philosophy, made such a joint collaboration impossible.
So we decided to encourage both groups to work on the development with the objective of only promoting one package when done.
It turned out both packages exceeded our expectations.
Both are being promoted since each one offers a unique approach.
Here is a summary of the particular features of each package.
- - - - UNDER CONSTRUCTION - - - -
In the FactSage Main Menu Window click Documentation for detailed information on the public compound and solution databases.
The following new options have recently been added to Data Search Window.
Private databases in \PRIVDATA
- this option, introduced in FactSage 8.3, applies to all private compound (*.cdb) and solution (*.sln,*.fdb) databases
that are stored in the \PRIVDATA folder (typically c:\FactSage\PRIVDATA).
These databases are automatically registered and added to the 'List of databases' posted in the Data Search Window.
The old manual way is still available (click 'Add/Remove Data > Add > filename etc.')
but storing the files in the \PRIVDATA folder avoids performing this manual task.
FTionx databases
- this option, new in FactSage 8.4, offers FTionx
- the new FACT Ionic Organics Databases
The FactPS 8.4
exclusion file has been updated.
The file is consulted when a given compound is listed in more than one database.
For example MgSnO3, Mg2SnO4, Na2S2O7, ... (see above) are oxides that have been added to
FactPS 8.4
and these compounds are also stored in FToxid.
When FactPS
and FToxid databases are selected, if a user selects say all solids in the Equilib Menu Window,
the exclusion file will avoid a duplicate selection by only selecting the FToxid compounds.
This is a simple example with oxides where the selection priority is obvious.
But when more than one FACT compound database is selected and it involves say metals, alloys, oxides, salts, etc.
there is a priority among competing databases that may not be not so evident.
This is where the exclusion file plays an important role in avoiding the duplicate selection of compounds.
In FactPS 8.4
there are 91 elements with a total of 5203 compounds (was 5038 in 8.3) and 7373 phases (was 7167).
In FactSage 8.4 the updates to FToxid include the following:
The FTsalt databases contain data for pure salts and salt solutions of 29 main cations:
and 15 main anions:
F, Cl, Br, I, NO2, NO3, ClO4, OH, CO3, SO4,
S2O7, CrO4, Cr2O7, MoO4, Mo2O7
as well as for dilute solutions of O2- and OH- in the molten salt phase.
In FactSage 8.4 the updates to FTsalt include the following
Also, compressibility expressions
(as a function of temperature) have been modified for the following pure liquid salts:
LiCl, NaCl, KCl, RbCl, CsCl, MgCl2, CaCl2, SrCl2, BaCl2, LiF, NaF, KF, RbF, CsF, MgF2,
CaF2, LiBr, NaBr, KBr, RbBr, CsBr, MgBr2, LiI, NaI, KI, RbI, CsI, Li2CO3, Na2CO3, K2CO3,
LiNO3, NaNO3, KNO3, RbNO3, CsNO3, Li2SO4, Na2SO4, K2SO4, LiOH, NaOH, and KOH.
In the solution FTsalt database new liquid solutions SALTN
(Na, K // Cl, CO3, SO4, S2O7, CrO4, Cr2O7, MoO4, Mo2O7, O - diluted in oxides),
SALTO (Na, K, Zn, Pb // Cl) and SALTP (Na, K, Hg, Hg2 // Cl) have been added.
In the case of SALTN, the model for the Na, K // Cl, CO3, SO4, S2O7 sub-system
is identical to that in the FTpulp database.
In addition seven new solid solutions have been introduced :
one pyrosulfate solid solution (KPyr), one pyrosulfate/dichromate solid solution
(Na2S2O7), two dichromate/dimolybdate solid solutions (K2Cr2O7 and Na2Cr2O7),
and three molybdate/chromate/sulfate solid solutions (K2MoO4(s3), Na2MoO4(s1)
and Na2MoO4(s2)).
Several solid solutions have been extended :
addition of the CrO4[2-] and MoO4[2-] anions to the solid solutions Dbeta-K2SO4,
alpha-K2SO4, Glaserite, and Na2SO4-V; addition of the CO3[2-] and MoO4[2-] anions
to the Na2CrO4 solid solution; and addition of the SO4[2-] anion to the solid
solutions gamma-Na2CO3 and beta-Na2CO3.
The SALTN (Na, K // Cl, CO3, SO4, S2O7, CrO4, Cr2O7, MoO4, Mo2O7,
O - diluted in oxides) liquid solution is the only FTsalt molten salt solution
containing A2MO4 and / or A2M2O7 (with A = Na, K and M = Cr, Mo).
The SALTO (Na, K, Zn, Pb // Cl) liquid solution is the only FTsalt molten
salt solution containing both ZnCl2 and PbCl2.
The SALTP (Na, K, Hg, Hg2 // Cl) liquid solution is the only FTsalt molten salt solution containing HgCl2.
The total number of stored FTsalt phase diagrams
is now 419 (was 377 in 8.3).
FTsalt 8.4
is included in the FACT 8.4 package of databases.
Complete details on FTsalt 8.4 including all the phase diagrams are given in
Documentation in the FactSage Main Menu Window.
The FTmisc databases contain data for a variety of sulfides, alloys, etc.
The databases includes dilute alloys of Fe-liquid, Pb-liquid, Sn-liquid, Cu-liquid, Cd-liquid, Te-liquid, Sb-liquid,
Se-liquid, SeTe-liquid, SbPb-liquid and PbSb-liquid each with a limited number of components, valid over limited composition ranges
In FTmisc 8.3
the MAT2 liquid sulfide/metal solution, and all solid solutions and stoichiometric compounds compatible was moved
to the new FTsulf 8.3 database.
For the matte smelting system (S-Cu-Fe-Ni-Co-Pb-Zn-As), the remaining sulfide solid solutions and stoichiometric compounds are compatible with liquid matte [FTmisc-MATT]. This system has been superseded by the new FTsulf 8.3 database, which provides equally good or better results for most applications.
In FTmisc 8.4 the liquid steel solution FTmisc-FeLq has been updated:
Complete details on FTmisc 8.4 including all the phase diagrams are given in Documentation.
The FTionx databases contain data for pure ionic organics compounds and ionic organic solutions of 8 cations:
with C3MIm = 1-propyl-3-methyl-imidazolium, C4MIm = 1-butyl-3-methyl-imidazolium,
C3MPip = 1-propyl-1-methyl-piperidinium, C3MPy = 1-propyl-3-methyl-pyridinium,
C3MPyrr = 1-propyl-1-methyl-pyrrolidinium, C4MPyrr = 1-butyl-1-methyl-pyrrolidinium,
C2Py = 1-ethyl-pyridinium, and C4Py = 1-butyl-pyridinium.
and 6 anions:
In FTionx 8.4 there are currently:
For normal equilibrium calculations all the compounds tend to decompose into C(graphite, s) and gaseous products.
In order to inhibit these decomposition reactions
in FactSage, "virtual elements" (Qa, Qb, ..., Qh) with atomic weights of 0.0 have been used.
The total number of stored FTionx phase diagrams is 22.
For example, the following phase diagrams are polythermal projections of the liquidus surface.
In FTlite 8.4 the changes are extensive.
A total of 1017 binary systems (was 992 in 8.3)
have been evaluated, for most of them over the entire range of composition and for all stable phases.
Several binary systems were revised.
A matrix of assessed binary systems is shown here
for the major and minor alloying elements of Al-, Mg- and Ti-alloys.
Several dozens of ternary systems have been assessed, and important quaternary systems have also
been evaluated.
FTlite 8.4 contains 324 solution phases (vs 317 in 8.3) and 2304 pure compounds
(was 2145 in 8.3) with 2806 stoichiometric phases counting allotropic forms (2621 in 8.3).
The total number of stored FTlite phase diagrams is now 1077 (was 1045 in 8.3).
Complete details on FTlite 8.4 including all the phase diagrams are given in the
updated Documentation in the FactSage Main Menu Window.

FSlead
is designed for thermodynamic and phase equilibrium calculations involving Pb alloys.
In FSlead 8.4 (27 elements) a total of 238 binary systems (235 in 8.3) have been evaluated,
for most of them over the entire range of composition and for all stable phases.
A matrix of assessed binary systems is shown here for the major and minor alloying elements of Pb-alloys.
In addition, several dozens of ternary systems have been assessed, and important quaternary systems have also been evaluated.
The FSlead 8.4 database contains 127 solution phases (125 in 8.3) and 434 pure compounds (415 in 8.3) with 641 stoichiometric phases (618 in 8.3) counting allotropic forms.
Complete details on FSlead 8.4
including all the phase diagrams are given in
'Documentation' in the FactSage Main Menu Window.
The FactSage 8.4 database contains 46 elements:
The FactSage FSstel steel database is based on relevant steel sub-systems from the
old SGTE Solution database, but now incorporates updates of those systems as well as new published assessments.
"Tramp elements" have also been included to allow calculations relating to recycling and removal of unwanted impurities to be performed.
FSstel contains 381 completely assessed 61 partially assessed binary alloy systems,
together with approximately 168 ternary and 29 quaternary systems for which assessed parameters are available for phases of practical relevance.
It contains 181 solution phases and 1015 stoichiometric compounds.
In FSstel the following systems have been added or updated.
(1) Updates
Update of Mu_phase and Sigma phase for binary and ternary systems
Mu_phase and Sigma phase form extensive solid solutions in the Fe-Co-Cr-Mn-Mo-Nb-Ni-Ta system,
which is important for high entropy alloys, and Ni- and Co-super alloy systems.
Mu_phase and Sigma phase in binary and ternary systems were updated for better description of phase diagrams.
In several ternary systems, FCC, BCC, liquid and other solutions were also updated simultaneously.
Co-Mo system: change of Mu_phase, Sigma phase, liquid phase
(b) Ternary systems
Co-Fe-Mo system: update of Mu_phase, Sigma, FCC, Liquid

The new database FTionx is devoted to ionic organics systems ("ionx" stands for "ionics").
Currently, there are only "ionic liquid" compounds (also referred to as "room temperature molten salts").
Ionic liquids have a low temperature of fusion (with a higher limit usually set arbitrarily to 100C), and consist of organic cations (which are large and asymmetric), and organic or inorganic anions.
Work is in progress on Deep Eutectic Solvent (DES) systems.
