What databases are currently available in FactSage?
In FactSage you can access two types of thermochemical databases – compound (i.e. pure substances) and real solutions. Compound databases are mainly for stoichiometric solid, liquid and gaseous species such as SiO2(s), FeS(liq), SO2(g). Allotropes (for example graphite C(s1) and diamond C(s2)) and isomers (for example ethylene C2H4O(liq1) and acetylene C2H4O (liq2)) may be included. Data on a few non-stoichiometric compounds such as FeOx (x = 0.947) are also stored. Depending on the type of phase (solid, liquid, gas) and data availability, the stored properties include Delta H(formation, 298.15K, 1bar), S(298.15K, 1bar), Cp(T), magnetic coefficients (Curie or Neel Temperature and magnetic moment), molar volumes (298.15K, 1bar) coupled with expansivities and compressibilities as functions of T. Dilute aqueous solution data (Henrian activity coefficients) and non-ideal gas properties (using Tcrit., Pcrit., Vcrit., the acentric factor (omega) and the dipole moment) are also stored in the
