Lead zirconate titanate piezoelectric ceramic and preparation method thereof
The invention discloses a lead zirconate titanate piezoelectric ceramic. The lead zirconate titanate piezoelectric ceramic is prepared from the following raw materials in parts by weight: 55 to 75 parts of lead tetroxide, 0 to 6 parts of barium sulfate, 0.2 to 8 parts of strontium carbonate, 0.1 to 0.9 part of niobium pentoxide, 0.2 to 1 part of antimony pentoxide, 15 to 25 parts of zirconium dioxide and 8 to 15 parts of titanium dioxide. According to the lead zirconate titanate piezoelectric ceramic disclosed by the invention, an excellent lead zirconate titanate piezoelectric ceramic material is prepared by adopting a two-step sintering solid-phase synthesis preparation method, so that the high-temperature sintering time is effectively shortened, and the energy, the time and the production cost are saved to a certain extent. According to the two-step sintering method, by controlling the temperature change, grain boundary migration can be restrained, grain boundary diffusion can be kept in an active state, and therefore the purpose of completing sintering on the premise that grains do not grow up is achieved.
本发明公开了一种锆钛酸铅压电陶瓷，所述锆钛酸铅压电陶瓷由以下重量份原料组成：四氧化三铅55~75份、硫酸钡0~6份、碳酸锶0.2~8份、五氧化二铌0.1~0.9份、五氧化二锑0.2~1份、二氧化锆15~25份、二氧化钛8~15份。本发明所述的锆钛酸铅压电陶瓷采用二步烧结固相合成的制备方法，制备出优良的锆钛酸铅压电陶瓷材料，既有效缩短了高温烧结时间，又在一定程度上节省了能源和时间和生产成本；本发明所述的二步烧结法通过控制温度的变化，既能够抑制晶界迁移，又能保持晶界扩散处于活跃状态，以实现在晶粒不长大的前提下完成烧结的目的。
