PZT-based high-Curie-temperature piezoelectric ceramic and preparation method thereof
The invention discloses a PZT-based high-Curie-temperature piezoelectric ceramic and a preparation method thereof. The PZT-based high-Curie-temperature piezoelectric ceramic is prepared from the following raw materials in parts by weight: 100 parts of lead tetroxide, 26-28 parts of zirconium dioxide, 15-17 parts of titanium dioxide, 2.0-4.0 parts of niobium pentoxide and 0.1-0.2 part of lithium carbonate. The preparation method comprises the steps of LiNb03 synthesis, mixing, presintering, granulation, molding and plastic removal, sintering, electrode loading, polarization and measurement. Byintroducing a high Curie temperature component LiNb03 into the PZT, the Curie temperature Tc of the PZT-based piezoelectric ceramic is further increased, and the application of the piezoelectric ceramic in an extreme environment is expanded.
本发明公开了一种PZT基高居里温度压电陶瓷及制备方法，包括以下重量份数的原料：四氧化三铅100份、二氧化锆26‑28份、二氧化钛15‑17份、五氧化二铌2.0‑4.0份、碳酸锂0.1‑0.2份。经LiNb03合成、混料、预烧、造粒、成型及排塑、烧结、上电极、极化、测量制备而成。通过在PZT中引入高居里温度LiNb03组分，进一步提高了PZT基压电陶瓷的居里温度Tc，拓展了压电陶瓷在极端环境下的应用。
