摘　　要：　PZT(Pb(ZrxTi(1-x))O3)是一种典型的三方-四方钙钛矿结构的铁电陶瓷,其微观结构对材料的铁电性能有很大的影响.我们用粉末烧结法制备PZT,对纯相PT(PbTiO3)和PZ(PbZrO3)的工艺进行研究.用X射线衍射仪对不同工艺条件制备的PZT,PT及PZ进行了结构分析.认为在使用Pb3O4作原料时并不需要文献[田长生,许建军,方晓华.烧结温度对0.85PZN-0.10BT-0.05PT陶瓷相结构的影响[J].功能材料,1995,26(增刊):358-359;杨祖陪,高峰,周欣山等.含铅弛豫铁电陶瓷的制备技术[J].功能材料,1998,29(增刊):533-535]所报道的需使反应处于富铅状态;计算分析还表明通过配比控制,可以使PZT的四方度符合使用要求.分析PZT中三方-四方相的共存与转变,认为其与内应力有关.PZT(Pb(Zr\-\%x\%Ti\-\{(1-\%x\%)\})O\-3) is a typical rhombohedraltetragonal ferroelectric ceramic. The microstructure of PZT have great influence on the ferroelectric character. PZT, pure phase PZ (PbTiO\-3) and PZ (PbZrO\-3) were made by powder sintering. The structure of PZT, PT and PZ made in different conditions were investigated by XRD. When using the Pb\-3O\-4 as the materials, the reaction can occur without richPb. Investigation shows that tetragonal degree of PZT meet the requirement through controlling compounding ratio. The coexisting and change of rhombohedraltetragonal phase of PZT have relation with internal stress.
