Lead-free piezoelectric ceramic material and preparation method thereof
The invention discloses a lead-free piezoelectric ceramic material and a preparation method thereof. The molecular formula of the ceramic material is (0.93-x)Bi<0.5>Na<0.5>TiO<3>-0.07Ba(Zr<0.055>Ti<0.945>)O<3>-x(K<0.5>Na<0.5>)NbO<3>, and x is greater than or equal to 0 and less than or equal to 0.07. The preparation method of the ceramic material comprises the following steps: proportioning, ball-milling, pre-sintering, secondary ball-milling, adding an adhesive, sieving and granulating, forming, removing plastic and sintering. The prepared lead-free piezoelectric ceramic has excellent electrical properties, meanwhile, the ceramic material is simple in formula and simple in synthesis process, and can replace PZT ceramic in some aspects.
本发明公开一种无铅压电陶瓷材料及其制备方法，所述陶瓷材料的分子式为：(0.93‑x)Bi0.5Na0.5TiO3‑0.07Ba(Zr0.055Ti0.945)O3‑x(K0.5Na0.5)NbO3，其中，0≤x≤0.07。该陶瓷材料的制备方法包括：配料、球磨、预烧、二次球磨、加粘合剂、过筛造粒、成型、排塑、烧结。本发明制得的无铅压电陶瓷具有优异的电学性能，同时，本发明中的陶瓷材料配方简单、合成工艺简单、在某些方面可以取代PZT陶瓷。
