Abstract
The phase tree of the previously studied СаO–MgO–SiO2 system was constructed. The phase tree includes three cycles. The phase tree is represented by fifteen simplices separated by fifteen stable secants. The formation of six double and four ternary compounds of congruent and incongruent melting was noted in the system. On the basis of the phase tree, taking into account the data on faceting elements, a forecast of crystallizing phases in stable secants and in phase secondary triangles was carried out. For the figurative points of the composition, corresponding to the intersections of stable and unstable secants, the chemical interaction is described on the basis of thermodynamic data. It has been shown that ternary compounds can be synthesized by several reactions.
