Lead magnesium niobate-lead zirconate titanate based piezoelectric ceramic material and preparation method thereof
The invention discloses a lead magnesium niobate-lead zirconate titanate based piezoelectric ceramic material and a preparation method thereof. The general formula of the piezoelectric ceramic material is as follows: Pb < 0.92 > Sr < 0.06 > Ba < 0.02 > (Mg < 1/3 > Nb < 2/3 >) < 0.25 > Ti < 0.40 > Zr < 0.35 > O < 3-x > wt% MnCO3, wherein x is more than 0.0 and less than or equal to 1.0. The piezoelectric coefficient d33 of the lead magnesium niobate-lead zirconate titanate based piezoelectric ceramic material prepared by the invention can reach 530pC/N, and the mechanical quality factor Qm can reach 624; the preparation process is simple in step, easy to operate, good in repeatability and high in yield; in the sintering process, powder with the same components is adopted as a protective atmosphere for powder burying, and element loss is avoided.
本发明公开了一种铌镁酸铅‑锆钛酸铅基压电陶瓷材料及其制备方法。本发明所述压电陶瓷材料的通式如下：Pb0.92Sr0.06Ba0.02(Mg1/3Nb2/3)0.25Ti0.40Zr0.35O3‑xwt％MnCO3，其中0.0＜x≤1.0。本发明制备的铌镁酸铅‑锆钛酸铅基压电陶瓷材料的压电系数d33可达530pC/N，机械品质因数Qm可达624；且制备工艺步骤简单、易于操作、重复性好、成品率高；烧结过程中采用相同组分粉料作为保护气氛进行埋粉，避免了元素的损失。
