Novel piezoelectric ceramic powder refining method and piezoelectric ceramic
The invention relates to the technical field of piezoelectric ceramic application, in particular to a novel piezoelectric ceramic powder refining method and piezoelectric ceramic. The piezoelectric ceramic is prepared by adopting a wet ball milling method and a sand mill refining method. The preparation method comprises the main steps of burdening, mixing, presintering, sand milling, sieving, forming and plastic discharging, sintering, electrode loading and polarization treatment and piezoelectric property measurement. By introducing a sand mill and adopting wet ball milling and multiple timesof refining treatment of the sand mill, the ball milling and stirring time before spray granulation is shortened, the granularity and the sintering temperature of the piezoelectric ceramic powder arereduced, the piezoelectric property of the material is improved, and the production efficiency and the practicability are greatly improved.
本发明涉及压电陶瓷应用领域技术领域，具体涉及一种新型压电陶瓷粉体细化方法及压电陶瓷，采用湿法球磨和砂磨机细化法制备，其主要步骤包括：配料—混料—预烧—砂磨—过筛—成型与排塑—烧结—上电极和极化处理—压电性能测量，本发明通过引入砂磨机，采用湿法球磨和砂磨机多次细化处理，缩短了喷雾造粒前球磨搅拌的时间，降低了压电陶瓷粉体的颗粒度和烧结温度，提升了材料的压电性能，大大提高了生产的效率和实用性。
