Lead zirconate titanate-based piezoelectric ceramic for high-power scene and preparation method of lead zirconate titanate-based piezoelectric ceramic
The embodiment of the invention discloses lead zirconate titanate-based piezoelectric ceramic for a high-power scene and a preparation method of the lead zirconate titanate-based piezoelectric ceramic, and relates to the technical field of piezoelectric ceramic and preparation thereof. The preparation method comprises the following steps: weighing powder raw materials according to a stoichiometric ratio, and putting the powder raw materials into a wet planetary ball mill for treatment to obtain ceramic powder; adding a binder into a part of the ceramic powder, granulating, aging, pressing into a green body, and heating and removing plastic from the green body to obtain a ceramic body; putting the ceramic green body into a high-temperature furnace, covering the ceramic green body with the ceramic powder, and sintering to obtain a ceramic wafer; and processing the ceramic wafer, and then carrying out polarization to obtain the lead zirconate titanate based piezoelectric ceramic. Therefore, the comprehensive performance of the high-power piezoelectric ceramic based on the PMS-PZT is further improved, and the application range of the piezoelectric ceramic material in a piezoelectric high-power application scene is widened.
本发明实施例公开了一种用于大功率场景的锆钛酸铅基压电陶瓷及其制备方法，涉及压电陶瓷及其制备技术领域。本发明包括：按照化学计量比称量粉体原料，放入湿式行星球磨进行处理得到陶瓷粉体；先向一部分的所述陶瓷粉体中加入粘结剂进行造粒再进行陈化，之后压制成生坯，再对生坯进行升温排塑，得到陶瓷坯体；将所述陶瓷坯体放入高温炉中，并利用所述陶瓷粉体覆盖所述陶瓷坯体，之后进行烧结得到陶瓷片；对所述陶瓷片进行加工，之后进行极化，得到所述锆钛酸铅基压电陶瓷。从而进一步提高了基于PMS‑PZT的大功率压电陶瓷的综合性能，提高了这种类型的压电陶瓷材料在压电大功率应用场景中的应用范围。
