Oxides and oxide solutions (solid and liquid) formed among Al 2O 3, The latter contain the properties of stoichiometric compounds, either obtainedįrom optimizations or taken from standard compilations. The former contain the optimized parameters for solution phases. Using the FactSage Gibbs energy minimization software.įactSage accesses both "solution" databases and "pure compound"ĭatabases. The resulting database of model parametersĬan be used for calculating phase equilibria and thermodynamic properties Usually be estimated with good accuracy from the optimized model parameters In particular, properties of multicomponent solutions can In the data can often be resolved, and the data can be properly interpolatedĪnd extrapolated. In suchĪn "optimization", all data are rendered self-consistent, discrepancies Simultaneously in order to obtain one set of model equations for the GibbsĮnergies of all phases as functions of temperature and composition. Based on proper thermodynamic models for every phase,Īll available thermodynamic and phase equilibrium data for a system are evaluated The solution databases (for solutions of oxides, salts, metals, etc.) haveĪll been developed by evaluation and "optimization" of data from Thermodynamic databases for inorganic systems in the world. The Fact and FactSage databases are the largest set of evaluated and optimized TDnucl and TDmeph - IRSN nuclear databases
