PZT(Pb(ZrxTi1-x1-xO3))是一种典型的菱面体四方铁电陶瓷。PZT的微观结构对其铁电性能有很大影响。采用粉末烧结法制备了PZT、纯相PZ(PbTiO3)和PZ(PbZrO3)。用X射线衍射仪研究了不同条件下制备的PZT、PT和PZ的结构。当以Pb3O4为原料时，反应可以在没有富的情况下进行。研究表明，通过控制配料比，PZT的四方程度满足要求。三方相四方相的共存和变化与内应力有关。
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.
