Physicochemical Interactions in Systems Formed by Trivalent REM with Group IVp Elements. Part 2. Phase Diagrams

A major aspect is considered of the physicochemical interaction in binary systems formed by REM with group IV p elements, namely the phase diagrams. The general regularities and the differences between these phase diagrams are considered for REM – X systems (X = Si, Ge, Sn, and Pb), particularly the relationship between the phase diagram topology and the crystallochemistry of the compounds formed. A comparison is performed for predicted and experimentally constructed phase diagrams.
