Chemical interaction in the five-component mutual system of fluorides, chlorides, metavanadates of lithium, sodium, and potassium

Crystallization tree of a five-component mutual Li, Na, K, //F, Cl, VO3 system is constructed using a complex DTA. Temperatures and the character of nonvariant equilibrium points in phase single units and a phase single unit with the minimal melting point of eutectic composition are revealed. Overall reactions, the most branched of them being confirmed by x ray phase analysis, are presented, which proves the correctness of the chemical interaction description in the five component system on the whole. 7 refs.; 6 tabs
