摘要/Abstract

摘要： 采用反应性熔盐法，以K₂Se₃：Zr：Q（Q＝Se，Te）＝1：1：5的摩尔比，在500℃下反应五天，生成黑色针状晶体（a）和（b）．元素分析结果表明晶体（a）和（b）分别为新的三元金属硫族化合物KZrSe₆和KZrTe₆，KZrSe₆和KZrTe₆晶体具有热力学介稳相的某些结构特征．

Abstract: The new ternary metal chalcogenides, KZrSe₆ and KZrTe₆, were synthesized by the reactive fiux method at intermediate temperature. The reaction of Zr metal with K₂Se₃/Q (the mole ratio K₂Se₃:Zr:Q=1:1:5, Q=Se, Te) at 500℃ for 5 days leads the formation of the title compounds. Both KZrSe₆ and KZrTe₆ crystals are black needles. They have some characterastics of thermodynamically metastable phases.

Key words: KZrSe₆, KZrTe₆, reactive flux method, solid state synthesis, thermodynamically metastable phases
