Sn-Ge modified BCZT lead-free piezoelectric ceramic
The invention discloses Sn-Ge modified BCZT lead-free piezoelectric ceramic, and belongs to a piezoelectric ceramic material. The component formula of the material is Ba < 0.85 > Ca < 0.15 > (Zr < 0.09 > Ti < 0.91-x-y > Sn < x > Ge < y >) O < 3 >, wherein x = y = 0 wt%, 0.008 wt%, 0.016 wt%, 0.024 wt%, 0.032 wt% and 0.04 wt%; the preparation method comprises the following steps: burdening according to the component formula, and then carrying out ball milling, pre-sintering, secondary ball milling, spray granulation, tabletting forming, glue discharging sintering, silver printing and polarization. According to the ceramic, d33 is equal to 368 pC/N, and kp is equal to 0.48; the preparation method is simple, has no special requirements on equipment, and is low in cost and small in environmental pollution. The piezoelectric ceramic material is a lead-free piezoelectric ceramic material.
本发明公开了一种Sn‑Ge改性BCZT无铅压电陶瓷，属于压电陶瓷材料；其组分式为Ba0.85Ca0.15)(Zr0.09Ti0.91‑x‑ySnxGey)O3，x＝y＝0wt％、0.008wt％、0.016wt％、0.024wt％、0.032wt％、0.04wt％；其制备方法是按所述组分式配料，然后球磨、预烧、二次球磨、喷雾造粒、压片成型、排胶烧结、印银、极化。本发明陶瓷d33＝368pC/N，kp＝0.48；不仅制备方法简单、对设备无特殊要求，而且成本低、环境污染小。是一种无铅压电陶瓷材料。
