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)
FactSage 7.3 (2019) FactSage 8.0 (2020) FactSage 8.1 (2021) FactSage 8.2 (2022)

FactSage 6.1 (2009)

Click on 'Summary' for a summary of all databases. It now includes details of databases in folders other than \FACTDATA\.
When you click on 'Add' to add a database to the list of databases accessible to FactSage, with solution ASCII files (ex: solution.dat) the program now checks to make sure the file does not contain illegal {Tab} settings. In such cases the positions of the offending tabs are listed.
A new 'Trans.' tab has been added that lists the transition temperatures and corresponding enthalpy changes between the stable standard state phases. As before, these values can still be determined via the Reaction module. Transitions involving the dilute aqueous phase, aq, are ignored.

FactSage 6.2 (2010)

A list of atomic weights for all elements has been added to the View Data Window - click on 'Atomic Weights'. The list includes the changes in FactSage 6.2 for about 50 elements. Most changes are very minor. The atomic weights are taken from

NIST

FactSage 6.4 (2013)

New Dropdown Menus

'Edit > Sort the list of compounds'

Prior to 6.4 the compounds displayed in View Data were only sorted by atomic number. In FactSage 6.4 with the 'Edit' dropdown menu it is now possible to sort the compounds :

by alphabet
by atomic number
by charge
by database
by first phase
by formula weight
by non-stoichiometric first
by number of atoms
by number of elements
by number of phases

with a restriction on the type of phases :

All Phases
Gas Phases
Liquid Phases
Aqueous Phases
Solid Phases

'<< Back to Menu'

You return to the View Data Menu Window by clicking on 'File > New ' or more simply by clicking on the new '<< Back to Menu'.

H(T) - H(298)ref
Tables of thermochemical data for all phases of a compound now include a column for H(T) - H(298)ref.

H(T) - H(298)ref values could also be displayed using the Reaction module, for example
SiO2 = SiO2 (298.15,1,s1) (T,1,s1)

FactSage 7.0 (2015)

Solution Dropdown Menu

Prior to 7.0 it was not possible to list all the phases in a solution database. In FactSage 7.0 the search option for 'all' elements is now included.

With the new 'Sort Solutions' dropdown menu it is also possible :

to display all the solutions and sort the phases :

by phase number
by alphabet (see screenshot below)
by number of species
by number of elements
by solution model #

with a restriction on the output :

list all species
do not list all species (see screenshot below)

Solution Data

In FactSage 7.0 it is possible to display the solution data (interactions and expressions) that have been stored in a private database (i.e. soln*.sln file).

Screenshot of View Data showing the display of solution data that have been stored
in the private database Copysoln.sln (data imported from ExamSoln.dat - see above).

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 25^oC - 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 25^oC. 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 G^o formation at 298 K - no H, S or Cp data

S2 - Delta G^o formation and S^o at 298 K - no H or Cp data

S3 - Delta G^o formation, S^o and Cp at 298 K

Aq - Delta G^o 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.

FactSage 8.1 (2021)

Vitual Species - Qa, Qb, Qc ... Qz

In FactSage 8.1 it is possible to create private databases containing "virtual elements" Qa, Qb, Qc ... Qz.
These private databases may be accessed by View Data in the usual manner.
The screenshot is a partial listing of virtual compounds stored in the VIRT database.
