Barium calcium zirconate titanate piezoelectric ceramic tape casting slurry and application thereof
The invention discloses barium calcium zirconate titanate piezoelectric ceramic tape casting slurry and application thereof. The barium calcium zirconate titanate piezoelectric ceramic tape casting slurry is prepared by taking barium carbonate, calcium carbonate, zirconium dioxide and titanium dioxide as base powder raw materials, barium titanate as a seed crystal and absolute ethyl alcohol as a solvent, carrying out ball milling, adding a dispersing agent, a plasticizer, a binder and a defoaming agent, and carrying out ball milling to form the barium calcium zirconate titanate piezoelectric ceramic tape casting slurry. The special tape casting formula for the BCZT-based powder has the beneficial effects that the special tape casting formula for the BCZT-based powder is used for a tape casting process to form a thin film so as to prepare high-performance BCZT piezoelectric ceramic, and when the thickness of the tape casting thin film is 50 microns, the dielectric constant and the piezoelectric constant are relatively high, and meanwhile, the sintering temperature is lowest.
本发明公开了一种锆钛酸钡钙压电陶瓷流延浆料及其应用。该锆钛酸钡钙压电陶瓷流延浆料是以碳酸钡、碳酸钙、二氧化锆和二氧化钛为基粉原料，以钛酸钡为晶种，以无水乙醇为溶剂，球磨，添加分散剂、增塑剂、粘结剂和消泡剂后，球磨，形成锆钛酸钡钙压电陶瓷流延浆料。本发明具有为BCZT基粉料的专用流延配方，用于流延工艺，形成薄膜，以制备高性能BCZT压电陶瓷，且流延薄膜厚度为50微米时，介电常数和压电常数较高，同时烧结温度最低的有益效果。
