FactSage SGnucl SGTE nuclear database
List of systems and phases
The following tables summarise the contents of the FactSage SGnucl SGTE nuclear database in terms of the systems and phases it includes. The listings assist in phase selection for particular calculations by providing
- A LIST OF all the unary, binary AND ternary SYSTEMS WHICH HAVE BEEN ASSESSED
- A LIST OF ALL ASSESSED phases IN EACH OF THE SYSTEMS
- ASSiSTANCE WITH PHASE SELECTION
Phase diagrams have been calculated for all the binary systems using the assessed parameters contained in the database. The diagram for a particular binary system can be viewed by clicking on the system as listed in Table 2 below. The diagrams contain the names of the stable phases in each system and thus provide guidance in phase selection for calculations in higher-order systems.
The phases listed for the binary and higher order systems may be solution phases or stoichiometric intermetallic compound phases (ST).
Use of the FactSage module VIEW DATA with NUCL compound and solution databases allows inspection of a phase listing for a defined combination of elements.
When searching for a particular system in the present four lists, use alphabetical order of the elements.

Complete assessments are available for the systems listed below.
Click on the system name to view the stable phase diagram calculated with the stored parameters.
Phases accompanied by ST in parenthesis indicate a stoichiometric phase. These phases must be selected from the SGnucl compound base.
(I-option) – the phase displays a miscibility gap and must be selected with the I-option.

Table 3: List of phases for TERNARY systems
Assessed parameters are available for the phases listed below. Thermodynamic values for other ternary phases are obtained from the relevant binaries by application of the particular model used in the database.
Phases accompanied by ST in parenthesis indicate a stoichiometric phase. The phase must be selected from the SGnucl compound base.
(I-option) – the phase displays a miscibility gap and must be selected with the I-option.
Comments in red for each system provide a rough guideline with respect to composition ranges covered by the assessed data and hence to which calculations should be restricted. Beware - if some ternary phases are unknown, or have not been included in the published assessments from which the present data have been selected, incorrect phase equilibria may be calculated.
