摘　　要：以硝酸铅、六水合硝酸镁、草酸铌、钛酸丁酯为前驱体原料,去离子水、乙二醇为溶剂,柠檬酸为螯合剂,铅、镁、铌、钛离子比为1:(1-x)/3:2(1-x)/3:x,其化学式为(1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3,采用溶胶-凝胶法经1150℃焙烧制备得到了单一相钙钛矿结构的PMNT粉末.The PMNT powders were synthesized by sol-gel process.Lead nitrate,magnesium nitrate hexahydrate,niobium oxalate and tetrabutyl titanate serve as the precursor materials.The deionized water, ethylene glycol are used as solvent,the citric acid is used as a chelating agent.The ratio of Pb2＋：Mg2＋：Nb5＋：Ti4＋ is 1：（1-x）/3：2（1-x）/3：x.It reveals that the powders sintered at 1 150℃have only perrovskate phase by XRD.
