What's New in View Data

What follows are summaries of the more important programming changes in View Data that have appeared in:


FactSage 6.1 (2009)


FactSage 6.2 (2010)


FactSage 6.4 (2013)


FactSage 7.0 (2015)


FactSage 7.2 (2018)

  • New Composition Tab

    There is a new View Data Composition Tab that displays the moles and weight% of the pure substances (compounds).

    The screenshot shows the View Data Composition Tab for FeAl2O4.

  • .

  • Export to Excel

    You can now export any View Data tabular display to an Excel file (.xls,.xlsx).

    Click on 'File > Save as > Save as type Excel ...'

    The screenshot shows the Excel spreadsheet for the above View Data Composition Tab.

  • .

  • One-Component Solutions

    With FactSage 7.2 it is now possible to list one-component solutions.

    This is important when listing the phases in the SGTE databases where one-component solutions are routinely selected in Equilib and Phase Diagram calculations (in the Reactants/Components Window click on 'Data Search > Options > Limits > Minimum solution components ..').

    It should be noted that for calculations with the FACT databases (FToxid, FTsalt, FTlite, etc.) the recommended minimum number of solution components is 2.

  • .


FactSage 7.3 (2019)

  • What's New in View Data - 'View Data > Help > What's New in View Data ...'

    The new link What's New in View Data gives a summary of the more important programming changes in View Data that have appeared since FactSage 6.1 (2009).


  • Limited data species

    Limited data species are solid and liquid compound and aqueous species that have limited data at 25oC - for example the Gibbs energy of formation at 298.15 K is known but not the Cp and enthalpy data.

    The limited data species are not retrieved when scanning the databases in Predom, EhpH, Equilib and Phase Diagram calculations because they cannot be used at temperatures other than 25oC. In most cases the species are unimportant anyway.

    However the limited data species are accessible to View Data and Reaction.

    The top screenshot is the View Data Cp(T) tab display of Zn(OH)2 and shows the data for 4 phases (3 allotropes and 1 aqueous).

    • S1 - Delta Go formation at 298 K - no H, S or Cp data

    • S2 - Delta Go formation and So at 298 K - no H or Cp data

    • S3 - Delta Go formation, So and Cp at 298 K

    • Aq - Delta Go formation at 298 K - no H, S or Cp data




    The bottom screenshot shows the tabular output for the temperature range 298.15 - 500 K.

    In FactSage 7.3 the restrictions are now clearly indicated. In View Data (and Reaction - not shown here) all the phases of Zn(OH)2 are accessible but the phases with limited data are only accessible at 298.15K.

  • Displaying references and comments stored in compound databases

    In View Data the compound reference numbers, when available, are listed on the right hand side in the Refs. column. These reference numbers only apply to the phases.

    There may be references for the compound that do not appear in the Refs. column. All compound and phase reference numbers are now listed at the top. The actual reference citations can be displayed by clicking the Refs. tab.

    The screenshot on the right shows all references associated with SiO2 taken from the FactPS compound database.


    In View Data there is a new option in the 'Sort Compounds' dropdown menu to list all the references stored in a compound database.

    This option is mainly applicable to the FACT (FT) databases where there are extensive lists of references.

    The screenshots show how to list the reference numbers stored in the FactPS compound database.


    Compound reference numbers are stored in the FactPS compound database but are not available for SGTE compound database.

    However there may be 'comments' associated with each compound. Such comments can now be displayed by clicking the Refs. tab.

    The screenshot shows the comments associated with Co taken from the SGPS compound database.


    FactSage 8.0 (2020)

  • Total number of components

    The summary of data for compounds now includes the total number of components (elements).

    For example the FactPS pure substances database includes 91 elements.
