摘要
应用低温溶剂热方法合成了(ＮＨ４)２ＷＳ４和Ｋ２ＷＳ４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．
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.
