Ceramic slurry, piezoelectric ceramic layer, piezoelectric ceramic actuator and preparation method thereof
The invention discloses ceramic slurry, a piezoelectric ceramic layer, a piezoelectric ceramic actuator and a preparation method of the piezoelectric ceramic actuator. The ceramic slurry comprises potassium sodium niobate-based piezoelectric ceramic, a solvent, a plasticizer, a dispersing agent and a binder. According to the ceramic slurry provided by the invention, by adding the plasticizer, the obdurability of a ceramic green body prepared from the ceramic slurry can be improved, and by adding the plasticizer, the obdurability of the ceramic green body prepared based on the ceramic slurry can be improved; by adding the dispersing agent, the potassium-sodium niobate-based piezoelectric ceramic powder can be fully dispersed in the slurry, so that the phenomena of layering and flocculation are prevented, and the stability of the slurry is improved; by adding the binder, the strength and density of a green body prepared based on the ceramic slurry can be improved, and the solvent is a carrier of other components in the ceramic slurry.
本申请公开了一种陶瓷浆料、压电陶瓷层、压电陶瓷致动器及其制备方法，该陶瓷浆料包括以下组分：铌酸钾钠基压电陶瓷、溶剂、增塑剂、分散剂和粘结剂。本申请提供的陶瓷浆料，通过添加增塑剂可以提升陶瓷浆料制成的陶瓷生坯的强韧性，通过添加增塑剂可以提升基于陶瓷浆料制得的陶瓷生坯的强韧性；通过添加分散剂能够将铌酸钾钠基压电陶瓷粉体充分分散于浆料当中，防止出现分层和絮凝现象，提升浆料的稳定性；通过添加粘结剂可以提升基于陶瓷浆料制得的生坯的强度和密度，溶剂是陶瓷浆料中其他组分的载体。
