一种不同温度预烧料混合的PZT压电陶瓷及其制备方法
技术领域
本发明涉及压电陶瓷技术领域，尤其涉及一种不同温度预烧料混合的PZT压电陶瓷及其制备方法。
背景技术
PZT压电陶瓷作为一种能实现机械能与电能相互转换新型的功能材料，广泛的应用于能源、机械、电子、国防等高技术领域。目前PZT压电陶瓷作为最为重要的商用功能陶瓷之一，近年来在大功率器件超声换能、超声马达、压电变压器、水声换能器及医用超声探头等方面得到了广泛使用。
随着各行各业的不断发展，对PZT压电陶瓷的性能要求也越来越高。因此如何提高PZT压电陶瓷的各项性能以满足日益提高的要求成为了热点。近年来，国内外的专家学者对PZT压电陶瓷的掺杂改性做了许多的研究，使其具备了更优异、更稳定的性能，使PZT陶瓷进入了一个新的发展阶段。但是，对于PZT陶瓷的预烧温度的研究报道却不是很多。
对于一般的PZT压电陶瓷而言，其制备工艺中的预烧过程十分重要，预烧是通过原料中原子或离子之间在加热作用下的扩散来完成固相化学反应，预烧过程中可以使各原料的固相化学反应充分均匀，生成固溶体，形成主晶相。不仅如此，预烧温度对压电陶瓷的压电性能和介电性能有十分重要的影响，这是因为合适的预烧温度能使原料之间的反应更加充分，有利于形成主晶相，使其在烧结过程中减小收缩率，形成的结构更为致密，进而使PZT压电陶瓷的性能提高。

将步骤(5)烧结后的压电陶瓷片在砂纸上研磨，采用丝网印刷工艺在其上下表面印刷银浆，置于加热炉中，升温至600-800℃并保温1-10min，自然冷却至室温；
(7)极化
将步骤(6)的烧银制品置于硅油中，施加直流电场，极化，然后自然冷却，得到本发明的PZT压电陶瓷。
