Description
技术领域
本发明涉及大功率高性能的无铅压电陶瓷材料，具体是一种ABO3型钙钛矿结构的具有高压电性能与高机械品质因数的低烧无铅压电陶瓷及其制备方法。
背景技术
压电陶瓷具有体积小，位移分辨率极高，响应速度快，响应速度快、低电压驱动、输出力大等特点，广泛应用于机电换能器，能将电信号与机械位移相互转换，并应用于传感器、调节控制系统。随着在生产中应用的扩展，压电陶瓷换能器逐渐向大功率、微型化方向发展，要求优良压电性能，高机械品质因数Q m、低介电损耗、低的烧结温度。
目前开发的无铅压电陶瓷材料，其压电性能远远低于商用的PZT体系陶瓷，并且软掺杂改性方法在提高压电性能的同时，其介电损耗增加，机械品质因数Q m降低，很难满足实际应用的要求。因此，研究与发展同时具有高压电性能、高机械品质因数Q m、低介电损耗、低烧结温度已经成为国内外当前研究的重点。
发明内容
本发明的目的是正对现有技术的不足，而提供一种同时具有高压电性能与高机械品质因数的低烧无铅压电陶瓷及其制备方法。这种陶瓷材料具有高压电性能、高机械品质因数Q m、低介电损耗、低烧结温度，环境友好、稳定性好、适合大功率换能器使用。这种方法的优点是制备工艺简单、成本低。
实现本发明目的的技术方案是：
一种同时具有高压电性能与高机械品质因数的低烧无铅压电陶瓷，组成通式为：(1-x)(Bi0.5Na0.5)1-2y (LiAl0.5Y0.5) y TiO3-x Ba(Ti0.9Mn0.1)O3+z(0.6BiVO4-0.4CuO)；其中x、y、z表示摩尔分数， 0<x<0.12，0<y<0.1，0<z<0.1。
上述同时具有高压电性能与高机械品质因数的低烧无铅压电陶瓷的制备方法，包括如下步骤：
(1)以电子级纳米粉体Bi2O3、Na2CO3、BaCO3、Al2O3、V2O5、CuO 、Y2O3、TiO2、Li2CO3、MnO2为原料，按照化学式(1-x)(Bi0.5Na0.5)1-2y (LiAl0.5Y0.5) y TiO3- xBa(Ti0.9Mn0.1)O3+z(0.6BiVO4-0.4CuO)，x、y、z表示摩尔分数， 0<x<0.12，0<y<0.1，0<z<0.1进行配料；
(2)以无水乙醇为介质球磨16小时，烘干，再在高铝坩埚中于760-820℃保温1小时预合成主晶相；
(3)以无水乙醇为介质球磨12小时，烘干后加入5%的PVA造粒；在150MPa压力下冷等静压成型；
(4)成型后的素坯在600℃保温2小时排胶，然后SPS快速烧结，在900-950℃保温10分钟，然后取出用风扇吹冷却；
(5)烧结后的样品加工成两面光滑、厚度约0.3mm的薄片，两面镀银电极然后通过交变电场循环极化，施加5个周期锯齿波循环极化，极化电场6000V/mm，频率0.5Hz，然后施加10个周期方波循环极化，极化电场7000V/mm，频率0.1Hz，极化温度80℃，放置24h后测试压电性能。
这种陶瓷材料通过A位复合离子 (Li+Al3+ 0.5Y3+ 0.5)以1/3价态1:1比例的小离子半径取代，产生A位有序-无序临界态结构陶瓷；通过纳米粉体获得组成与结构均匀的陶瓷材料，通过复合添加BiVO4/CuO烧结助剂，降低烧结温度。
这种方法采用SPS烧结，结合烧结助剂，烧结温度低，保温时间短，晶粒细小均匀，致密度高，结合风扇冷却适中的快速降温与循环极化工艺，有效排列电畴与有序缺陷，消除缺陷的不利影响，转为稳定电畴，可同时获得高压电性能、高机械品质因数、低介电损耗、低烧结温度。
这种陶瓷材料具有高压电性能、高机械品质因数Q m、低介电损耗、低烧结温度，环境友好、稳定性好、适合大功率换能器使用。这种方法的优点是制备工艺简单、成本低。
