| 摘 要： | 采用传统陶瓷烧结工艺合成了单一复合钙钛矿结构的Ｐｂ１－ｘＬａｘ（ＺｒｙＴｉｚＳｎ１－ｙ－ｚ）Ｏ３体系陶瓷（简称ＰＬＺＳＴ其中０．０１≤ｘ≤０．０５；０．３５≤ｙ≤０．７０；０．０５≤ｚ≤０．２０）．研究表明：在选定的工艺条件下，立方相和正交相ＰＬＺＳＴ易合成为单一复合钙钛矿结构，而四方相ＰＬＺＳＴ的合成较困难；采用多次球磨、加适量过量ＰｂＯ（３％）、控制成型压力、选择合适的烧结温度（１３５℃）有助于合成单一复合钙钛矿结构的ＰＬＺＳＴ．

| Abstract: | Pb1-xLax)(ZryTizSn1-y-z)O3(PLZST ,0.01≤ x ≤0.05 ; 0.355≤ y≤ 0.70;0.05≤ z≤ 0.20) ceramics with pure complex perovskite phase were fabricated by means of conventional solid state sintering technique. The study shows that it s easier to prepare PLZST ceramics with cubic or orthorhombic structure than those with tetragonal structure. The results also indicate that milling repeatedly, controlling the loss of PbO and sintering at high temperature (1350℃) contribute to the fabrication of the PLZST ceramics with single perovskite phase structure. |
