Production of barium molybdate and tungstate on the base of ternary reciprocal Na, Ba long Cl, EhO4 (Eh - Mo, W) systems

Possibilities of the syntnesis of barium molybdate and tungstate on the base of ternary reciprocal Na, Ba parallel Cl, EhO4 (Eh=Mo, W) system state diagrams are under study. It is shown that on the basis of these reciprocal state diagrams syntnesis of not only BaO4 but also of other suhstances is possible. Purity of obtained chemical agents is basically dependent on qualification of initial components. Synthesis temperature is decreased and time is reduced as compared to other known methods. For substance synthesis, state diagrams examination (reaction type confirmation and component crystallization fields separation from compound crystallization fields) is necessary along with the calculation of the conventional thermochemical effect
