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 (NH4) 2WS4 and K2WS4 crystals were synthesized by low temperature solvothermal method. The samples were characterized by XRD, SEM and ED. The results show that the method has the advantages of mild reaction conditions, easy operation and no pollution to the environment. The obtained crystal has good crystal appearance and crystal phase purity.
