水热法合成PLZT压电陶瓷粉体

Synthesis of PLZT Piezoelectric Ceramic Powder Through Hydrothermal Method

摘要: 采用水热法合成了PLZT (9/65/35)多晶陶瓷粉体。讨论了反应温度、反应时间、矿化剂浓度等不同工艺条件对PLZT晶化过程的影响;得到了一组可以合成出纯钙钛矿相PLZT的工艺条件,即当反应温度为200℃、矿化剂浓度为5mol、反应时间为12h时,生成的粉末为纯钙钛矿相结构。

Abstract: PLZTPb1-xLaz(Zr1-yTiy)(1-x)/4O4 polycrystal ceramic powder are synthesed through by drothermal method. The influences of reaction temperature, time and mineralizer concentration on the PLZT crystallization process are discussed. The results showed that the Perovskite structure can be obtained at reaction temperature 200℃, mineralizer concentration 5 mol and reaction time 12 h.
