Abstract

The phase relations for the systems AgI-NaI and AgI-KI have been determined for the temperature range from room temperature to 685° C, using differential thermal analysis techniques. The AgI-NaI system has a eutectic at 50 mole percent NaI and 384° C. The AgI-KI system has eutectics at 20.8 and 28.5 mole percent KI and 254° C and 244° C, respectively. A compound of formula KAgI is formed with a congruent melting point of 268° C.

摘要

利用差热分析技术，已测定了碘化银-碘化钠和碘化银-碘化钾体系在室温至685℃温度范围内的相关系。碘化银-碘化钠体系在50摩尔百分比的碘化钠和384℃时有一个低共熔物。碘化银-碘化钾体系分别在20.8和28.5摩尔百分比的碘化钾以及254℃和244℃时有低共熔物。形成了化学式为KAgI的化合物，其一致熔点为268℃。
