摘　　要：以硝酸铅(钕)、硝酸锆和钛酸丁酯为原料,采用固相反应法制备PbZr0.5Ti0.5O3和NdZr0.5Ti0.5O3陶瓷材料,利用XRD和高倍光学显微镜对产物进行了表征,并利用Radiant Precision Workstation铁电测试仪测试了两种材料的电滞回线,结果表明:在实验条件下,NdZr0.5Ti0.5O3的极化强度、剩余极化强度及矫顽电场分别为160μC·mm-2、126μC·mm-2、22.5kV·mm-1。用Nd取代Pb的NdZr0.5Ti0.5O3可获得较高的极化强度、剩余极化强度及矫顽电场。PbZr0.5Ti0.5O3 and NdZr0.5Ti0.5O3 ceramic materials were prepared by solid state reaction method with the raw materials of lead nitrate（Nd）,zirconium nitrate and butyl titanate.The products were characteristic by XRD and high-times optical microscope.Besides,ferroelectric hysteresis loop of the two materials were tested by Radiant Precision Workstation ferroelectric tester.The results indicate that polarization intensity,remanent polarization intensity and coercive electric field of NdZr0.5Ti0.5O3are 160μC·mm^-2,126μC·mm^-2,22.5kV·mm^-1,respectively.NdZr0.5Ti0.5O3 with Nd replacing Pb can gain high polarization intensity,remanent polarization intensity and coercive electric field.
