A general algorithm and a FORTRAN program for the calculation of isobaric phase diagrams of polymeric oxide systems based on the thermodynamic model of silicate melts was developed. This software enables the primary crystallization temperatures for a single configuration point to be determined and the phase diagrams for a binary or ternary systems to be constructed. The verification of the computational algorithm was demonstrated on simple ternary eutectic systems, a pseudoternary system with four crystallization phases and a ternary system in which some binary and ternary compounds are formed. The way of using this method in structural studies of silicate melts was described. |
