Abstract: | By differential thermal analysis, the coordinates of the following characteristic points in the KBr-KVO3-K2MoO4 system were determined: a eutectic in the KBr-KVO3 system (12% KBr, 88% KVO3, T melt = 458°C), a eutectic in the KBr-KVO3-K2MoO4 ternary system (12.8% KBr, 84.7% KVO3, 2.5% K2MoO4,T melt = 430°C), and also three points of polymorphic transitions in K2MoO4 ((1) δ ? γ: 21.7% KBr, 72.3% KVO3, 6% K2MoO4,T melt = 476°C; (2) γ ? β: 19% KBr, 78% KVO3, 3% K2MoO4,T melt = 450°C; and (3) γ ? β: 6% KBr, 89% KVO3, 5% K2MoO4,T melt = 450°C). For elements of the ternary system, phase equilibria were described. |
