Abstract

By differential thermal analysis, the ternary systems MCl–MI–M₂CrO₄ (M = Rb, Cs) were studied, and the characteristics (melting points, concentrations of components) of alloys at invariant equilibrium points of the systems were determined. The studied systems are systems of the same type that form by varying the alkali metal cation with increasing atomic number of the cation. In all the binary systems constituting the ternary systems, eutectics form. Based on analyzing the faceting elements, it was assumed that eutectics form in the ternary systems. Low-melting eutectic mixtures of alkali-metal halides and chromates are chemically stable even in the molten state and have low viscosity and low volatility, which makes them suitable for using as heat-storage materials or electrolytes for chemical current sources. Consideration of the systems MCl–MI–M₂CrO₄ (M = Li, Na, K, Rb, Cs) showed that the varying alkali metal cation in them does not affect the morphology of the liquidus.

三元体系RbCl–RbI–Rb 2 CrO 4和CsCl–CsI–Cs 2 CrO 4的相平衡研究

摘要

通过差热分析，三元体系MCl–MI–M ₂ CrO ₄研究了（M = Rb，Cs），并确定了系统不变平衡点处合金的特性（熔点，组分浓度）。所研究的系统是相同类型的系统，通过随碱金属原子数的增加而改变碱金属阳离子而形成。在构成三元系统的所有二元系统中，共晶形成。在分析刻面元素的基础上，假设共晶在三元体系中形成。碱金属卤化物和铬酸盐的低熔点共晶混合物即使在熔融状态下也具有化学稳定性，并且具有低粘度和低挥发性，这使其适合用作化学电流源的蓄热材料或电解质。考虑系统MCl–MI–M ₂ CrO ₄ （M = Li，Na，K，Rb，Cs）表明，其中变化的碱金属阳离子不会影响液相线的形态。
