摘要: 将湿化学法中的sol-gel技术与声化学中的超声雾化技术相结合,提出一种新的陶瓷粉体合成方法-湿声化学法, 并制备了PZT(52/48)粉体.结果表明, 用湿声化学法制备PZT(52/48)粉体, 在400℃开始形成PZT钙钛矿相,比其它制备方法的温度(500-900℃)低, 在700℃保温2 h即可得到具有纯PZT结构相的粉体.用湿声化学法制备的粉体颗粒呈圆形, 粒径小于1 um.湿声化学法使用不溶性盐ZrO2而不是sol-gel方法中必须使用的可溶性盐,从而降低了成本.

Abstract:Lead zirconate titanate (PZT) (52/48) powders were synthesized by Wet-acoustic chemical method. XRD results show that the perovskite phase of PZT is formed under 400℃, which is much lower than the calcinations temperature (500-900℃) require in other reaction process. Phase-pure PZT powders were obtained at 700°C. SEM results show that the powder particle is round and its size is within 1μm.
Key wordsPZT    Sol-gel    Wet-acoustic chemical method    Ultrasonic atomization
