www.factsage.com Demonstration3 Databases frame Databases In FactSage there are two types of thermochemical databases: compound (i.e. pure substances) databases: –Compound databases are for stoichiometric pure substances and include data for H(formation), S, C p (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 G E parameters of mixing between the phase constituents. FactSage 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.
