一种烟雾报警器专用压电振子瓷料配方及其制备方法
摘要：
本发明公开了一种烟雾报警器专用压电振子瓷料配方及其制备方法，涉及压电陶瓷领域。该压电振子瓷料属三元系（PSN-PZT）压电陶瓷，其配方化学计量通式为：Pb1-x-yMxZy（Sb1/3Nb2/3）0.02（Zr1/2Ti1/2）0.98，其中，x=0.0-0.15，y=0-0.15，M、Z包括化合物SrCO3、BaCO3、CaCO3、MgCO3中的至少两种；该压电振子陶瓷经过第一次球磨，第二次球磨，得到的筛下物料与粘结剂混合，造粒，压制成型进行排胶处理后用电极极化得到，本发明所公开的制备方法操作简单、稳定，产率高，适于工业化推广应用，制备的压电振子适用于烟雾报警器用的蜂鸣器。
摘要（英）：

The invention discloses a formula of special piezoelectric vibrator ceramic material for a smoke alarm and a preparation method of the piezoelectric vibrator ceramic material, and relates to the fieldof piezoelectric ceramics. The piezoelectric vibrator ceramic material belongs to ternary system (PSN-PZT) piezoelectric ceramic, a stoichiometric general formula of the formula of the ceramic material is Pb1-x-yMxZy(Sb1/3Nb2/3)0.02(Zr1/2Ti1/2)0.98, wherein x is 0.0-0.15 and y is 0-0.15, M and Z comprise at least two of compounds SrCO3, BaCO3, CaCO3 and MgCO3. The piezoelectric vibrator ceramic is obtained by steps as follows: first ball milling and second ball milling are performed, an obtained undersize material is mixed with a binder, granulated, pressed and molded, and a product is subjected to degumming and polarized by an electrode. The preparation method is simple and stable to operate, high in yield and suitable for industrial popularization and application, and a prepared piezoelectric vibrator is suitable for a buzzer for the smoke alarm.
