| 摘 要： | 研究了Ｐｈ（Ｚｎ１／３Ｎｂ２／３）ｘ（Ｆｅ１／２Ｎｂ１／２）０．６４－ｘ（Ｆｅ２／３Ｗ１／３）０．３６Ｏ３（ＰＺＮ－ＰＦＮ－ＰＦＷ）系陶瓷中ＰＺＮ含量与焦录石相形成间的关系，以及少量添加剂对钙钛矿相的稳定和介电性能的影响。在该系中仅添加０．１５ｗｔ％ＭｎＣＯ３就可制备１００％钙钛矿型结构的陶瓷。文中报导了该系组成的相关系和介电性质。钙钛矿结构的陶瓷介电常数高，电容温度系数较低。

| Abstract: | The relationship between formation of pyrochlore phate and amount of PZN in the PZNPEN-PEW system as well as the effect of a few amountof additive on the stabilization of perovskite phase and dielectric properties were stuided. Ceramics with 100% perovskite type structure were produced by the addition of only 0.15wt% of MnCO3 in this system.Phase relation of compositions and dielectric proPerties in the PZN-PEN-PFW system have been reported.Ceramics with perovskite structure possess high dieiestric constant and lower temperature cofficient of capcitance. |
