Piezoelectric ceramic piece for high-power piezoelectric vibrator and preparation method of piezoelectric ceramic piece
The invention discloses a piezoelectric ceramic piece for a high-power piezoelectric vibrator and a preparation method of the piezoelectric ceramic piece, and belongs to piezoelectric ceramic pieces and preparation methods of the piezoelectric ceramic pieces. The chemical formula of the piezoelectric ceramic material of the piezoelectric ceramic piece provided by the invention is Pb0. 95SrXBay (Zr0. 51Ti0. 49) 0.85 (Sb1/3Nb2/3) 0.05 (Ni1/3Nb2/3) 0.1 O3 + 0.1 wt% CuO + 0.3 wt% Bi2O3 + 0.5 wt% Li2CO3, wherein the sum of x and y is equal to 0.05. The preparation 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, printing an inner electrode, laminating, cutting, discharging adhesive and sintering, thereby obtaining the lithium ion battery. And printing silver paste, sintering silver and polarizing. The piezoelectric ceramic piece provided by the invention has excellent piezoelectric performance, also reduces the sintering temperature, reduces the volatilization of PbO, and can meet the use requirements of material conveying of a high-power piezoelectric vibrator.
本发明公开了一种大功率压电振动器用压电陶瓷片及其制备方法，属于压电陶瓷片及制备方法；本发明提供的压电陶瓷片的压电陶瓷材料组成化学式为：Pb0.95SrXBay(Zr0.51Ti0.49)0.85(Sb1/3Nb2/3)0.05(Ni1/3Nb2/3)0.1O3+0.1wt%CuO+0.3wt%Bi2O3+0.5 wt%Li2CO3，其中x+y=0.05。本发明提供的制备方法是：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、印刷内电极、叠片、切割，排胶烧结，印刷银浆、烧银、极化。本发明提供的压电陶瓷片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，可满足大功率压电振动器物料输送的使用要求。
