Co-fired large-displacement multilayer piezoelectric actuator and preparation method thereof
The invention discloses a co-fired large-displacement multilayer piezoelectric actuator and a preparation method thereof, and belongs to piezoelectric ceramics and a preparation method thereof. The chemical formula of the material composition of the co-fired large-displacement multilayer piezoelectric actuator provided by the invention is Pb < 0.95 > Sr < 0.05 > (Zr < 0.51 > Ti < 0.49 >) (Zn < 1/3 > Nb < 2/3 >) < 0.05 > (Ni < 1/3 > Nb < 2/3 >) < 0.1 > O < 3 + >, 0.1 wt% of CuO, 0.4 wt% of Bi2O3 and 0.5 wt% of Li2CO3. The method provided by the invention comprises the following steps: preparing materials according to the chemical formula, then carrying out ball milling, drying and pre-sintering, adding a sintering aid, then carrying out secondary ball milling and drying, then adding a solvent, a plasticizer, a defoaming agent and a dispersing agent, carrying out third-time ball milling, adding an adhesive, carrying out fourth-time ball milling, and then carrying out tape casting, electrode printing, lamination, isostatic pressing, cutting, hot pressing, cutting and adhesive discharging and sintering, thereby obtaining the lithium ion battery electrode. Printing silver, burning silver and welding an outer electrode. The sintering type large-displacement multilayer piezoelectric actuator provided by the invention has excellent piezoelectric performance, meanwhile, the sintering temperature is reduced, the volatilization of PbO is reduced, and the use requirement of a low-temperature co-sintering type piezoelectric actuator can be met.
本发明公开了一种共烧型大位移多层压电致动器及其制备方法，属于压电陶瓷及制备方法；本发明提供的共烧型大位移多层压电致动器的材料组成化学式为：Pb0.95Sr0.05(Zr0.51Ti0.49)(Zn1/3Nb2/3)0.05(Ni1/3Nb2/3)0.1O3+0.1wt%CuO+0.4wt%Bi2O3+0.5wt%Li2CO3。本发明提供的方法是按所述化学式配料，然后球磨、烘干、预烧，加入烧结助剂后进行二次球磨、烘干，然后加入溶剂、增塑剂、消泡剂以及分散剂进行三次球磨，加入粘合剂进行四次球磨，然后流延、印刷电极、叠片、等静压、切割、热压、裁切，排胶烧结，印银、烧银、焊接外电极。本发明提供的烧型大位移多层压电致动器在具有优良压电性能的同时还降低了烧结温度，减少了PbO的挥发，可满足低温共烧型压电致动器的使用要求。
