【摘要】 用溶胶－凝胶（Ｓｏｌ－Ｇｅｌ）法制备了ＰｂＺｒＯ３－ＰｂＴｉＯ３（ＰＺＴ）基四元系压电陶瓷（ＰＭＭＮ）。经Ｘ射线衍射分析、扫描电镜及密度测试表明，材料主晶相为四方晶系，所得陶瓷致密，晶粒均匀，具有较好的介电性能。更多还原

【Abstract】 Piezoelectric ceramics based on PZT ceramics are prepared in Sol-Gel processing. XRD and SEM are used to confirm the main phase of the material to be tetragonal PZT lattice.The PZT ceramics is dense with homogeneous grain size,and have good electric properties.更多还原
