Preparation method of barium titanate-based texture electrostriction multilayer ceramic driver
The invention relates to the technical field of preparation of electrostriction multilayer ceramic drivers, in particular to a preparation method of a barium titanate-based texture electrostriction multilayer ceramic driver. The preparation method comprises the steps of obtaining a single-layer texture green body through tape casting, conducting silk-screen printing on an inner electrode, conducting lamination hot pressing, conducting sintering to obtain the multilayer ceramic driver and the like. Compared with a barium titanate-based texture block ceramic driver, the barium titanate-based texture electrostriction multilayer ceramic driver prepared by the method has the advantages that the electrostriction strain reaches 0.157%, the electrostriction coefficient reaches 0.061 m < 4 >/C < 2 >, the electrostriction coefficient is increased by about 50% compared with the electrostriction coefficient of about 0.04 m < 4 >/C < 2 > of an untextured 0.5 Ba (Zr0. 2Ti0. 8) O3-0. 5 (Ba0. 7Ca0. 3) TiO3 ceramic matrix, and the effect is remarkable. The driving electric field is obviously improved, and meanwhile, more excellent electrostriction strain performance can be obtained under a high service electric field. The preparation method disclosed by the invention is simple and easy to implement, low in equipment requirement, easy in reaction condition control and good in repeatability.
