Abstract
Методом дифференциального термического анализа (ДТА) исследована трехкомпонентная система CsCl-CsBr-Cs2MoO4, а также элементы ее огранения – двухкомпонентные системы CsCl-Cs2MoO4 и CsBr-Cs2MoO4. В двухкомпонентных системах определены температуры плавления и составы точек нонвариантных равновесий. Фазовый комплекс системы CsCl-CsBr-Cs2MoO4 представлен тремя полями кристаллизации фаз – α-Cs2MoO4, β-Cs2MoO4 и полем непрерывного ряда твердых растворов CsClxBr1-x. Определены координаты минимума (условно-нонвариантное равновесие) на кривой моновариантных равновесий.

Triangle compositions of the ternary system CsCl–CsBr–Cs2MoO4 consists of the three binary systems: CsCl–CsBr, CsCl–Cs2MoO4, CsBr–Cs2MoO4
The experimental study of the ternary system from the chloride, bromide and molybdate cesium and binary system from the bromide and molybdate cesium are shown in the present work
