More Information
Summary:Disclosed are a BCTZ-based lead-free piezoelectric ceramic composition having improved piezoelectric properties and a method of manufacturing the BCTZ-based lead-free piezoelectric ceramic. The disclosed lead-free piezoelectric ceramic composition includes a BCTZ-based base material and copper oxide (CuO), in which a weight ratio of copper oxide is 0.2 wt% to 0.4 wt%. 압전 특성이 개선된, BCTZ계 무연 압전 세라믹 조성물 및 BCTZ계 무연 압전 세라믹의 제조 방법이 개시된다. 개시된 무연 압전 세라믹 조성물은 BCTZ계 모재료 및 산화구리(CuO)를 포함하며, 상기 무연 압전 세라믹 조성물에서, 상기 산화구리의 중량비는 0.2 wt% 내지 0.4 wt%이다.
