Description

Quaternary reciprocal system Na, K // F, CO3, MoO4 was investigated for the first time by the method of differential thermal analysis using projective geometry procedures. Its stable simplexes: (NaF)2 - (KF)2 - K2CO3 - KF · K2MoO4, (NaF)2 - K2CO3 - K2MoO4 - KF · K2MoO4, (NaF)2 - Na2CO3 - Na2MoO4, (NaF)2 - Na2CO3 - K2CO3 - K2MoO4 are recognized and studied. It is shown that quadrupole eutectic point are missing in the (NaF)2 - Na2CO3 - K2CO3 - K2MoO4 system as connected with the stability of binary solid solutions based on Na2CO3 and K2CO3. Coordinates of all six non variant points are ascertained by the method of differential thermal analysis

Abstract (Russian)

Методом дифференциального термического анализа с использованием приемов проективной геометрии впервые исследована четырехкомпонентная взаимная система Na, K // F, CO3, MoO4. Выявлены и изучены ее стабильные симплексы: (NaF)2 - (KF)2 - K2CO3 - KF · K2MoO4, (NaF)2 - K2CO3 - K2MoO4 - KF · K2MoO4, (NaF)2 - Na2CO3 - Na2MoO4, (NaF)2 - Na2CO3 - K2CO3 - K2MoO4. Показано, что в системе (NaF)2 - Na2CO3 - K2CO3 - K2MoO4 четверная эвтектическая точка отсутствует, что связано с устойчивостью двойных твердых растворов на основе Na2CO3 и K2CO3. Методом дифференциального термического анализа определены координаты всех шести нонвариантных точек
