摘要/Abstract

摘要： 应用低温溶剂热方法合成了(ＮＨ_４)_２ＷＳ_４和Ｋ_２ＷＳ_４晶体,并用ＸＲＤ、ＳＥＭ和ＥＤ对样品进行了表征．结果表明:这种方法反应条件温和,操作简便,对环境无污染;得到的晶体晶貌良好,晶相纯．

关键词: 溶剂热合成, 硫代钨酸盐, XRD、SEM和ED表征

Abstract: The tetrathiotungstate crystals (NH₄)₂WS₄ and K₂WS₄ were first synthesized by the solventothermal technique by using water-alcohol as solvent at low temperature, and characterized by SEM, XRD, ED techniques. Results show that their crystal phases are pure and their shapes are good. The synthesis procedure is simple and high yield, produces less pollution.

Key words: solventothermal synthesis, tetrathiotungstates, XRD, SEM and ED characterization
