Databases frame Databases In Fact. Sage there are two types of thermochemical databases: • compound (i. e. pure substances) databases: – Compound databases are for stoichiometric pure substances and include data for DH(formation), S, Cp(T), magnetic coefficients, molar volumes, expansivities(T) and compressibilities(P, T). • and real solution databases: – Solution data are for alloys, aqueous solutions, ceramics, salts, mattes, slags etc. – Data are stored as G functions for the phase constituents and GE parameters of mixing between the phase constituents. Fact. Sage supports 14 different solution models. Modules • View Data – lists the compounds and displays their data. – lists the solution phases. • Compound - enter pure substances data in your own compound databases • Solution - enter non-ideal mixing properties in your own solution database The next slides show the View Data module accessing the demonstration databases. Detailed examples are given in the complete Slide Shows. Demonstration 3 www. factsage. com
