摘　　要：本文从Ba（ZrxTi1-x）O3的x取值和介质碱度的变化研究BZT固溶晶体的形成．结果表明：在水热过程中同时形成以BaZrO3为主体、部分Zr被Ti取代和以BaTiO3为主体、部分Ti被Zr所取代的两种固溶晶体是BZT合成的实质，只有在特定的x值和相应的介质碱度下，才能合成单质的BZT固溶晶体.The formation of solid solution of Ba(ZrxTi1-x)O3 has been studied by varying the value of x and the basicity of hydrothermal medium. The results showed that two kinds of substitution solid solution crystal of Ba(ZrxTi1-x)O3 formed simultaneously during the hy-drothermal process. One crystal took BaTiO3 as the main frame with part of Ti substituted by Zr, and the other took BaZrO3 as the main body with part of Zr substituted by Ti. A uniform solution crystal of BZT existed only at particular basicity and x value.
