摘要
将凝胶注模成型技术应用于三元系压电陶瓷PMN-PZT的制备工艺中,重点讨论了分散剂、浆料pH值和固相含量对注模浆料粘度的影响,制备出固相含量高达55%(体积分数)、粘度<1Pa.s的压电陶瓷悬浮体,使用该浆料可获得达理论密度95%以上的致密PMN-PZT压电陶瓷。
In this paper, gelcasting was applied to preparation of PMN-PZT piezoelectric ceramics. The effects of dispersant, pH value and solid volume on viscosity of slurry were investigated. The piezoelectric ceramics suspension with 55vo1% solid loading and below 1Pa·s viscosity was prepared. And the piezoelectric ceramics with compact structure was produced by using this slurry.
