ABSTRACT:

Computer model of pseudo-ternary system Mg2SiO4–CaAl2Si2O8–SiO2 was elaborated based on data for structure of binary systems and the occurring invariant processes. Its Txy diagram contains the immiscibility surface, five liquidus surfaces, 23 ruled surfaces, 4 horizontal complexes at the temperatures of invariant points, 20 phase regions. The calculation of crystallization paths was carried out. Using the diagrams of vertical and horizontal mass balance permit to analyze the crystallization stages and obtain the sets of microconstituents for the given mass centers.
