LEAD-FREE PIEZOELECTRIC CERAMIC COMPOSITION AND METHOD FOR LEAD-FREE PIEZOELECTRIC CERAMIC

높은 압전 특성과 스피커 특성을 제공하는 BCTZ계 무연 압전 세라믹 조성물 및 BCTZ계 무연 압전 세라믹의 제조 방법이 개시된다. 개시된 무연 압전 세라믹의 제조 방법은 BCTZ계 모재료에 산화 구리가 첨가된 혼합물을 제조하는 단계; 및 1300도(℃) 내지 1600도(℃)의 온도에서, 1시간 내지 5시간동안 상기 혼합물을 소결하는 단계를 포함하며, 상기 혼합물에서 상기 산화 구리의 중량비는 0.6wt%이다.

Disclosed are a BCTZ-based lead-free piezoelectric ceramic composition and a method of preparing a BCTZ-based lead-free piezoelectric ceramic which provide high piezoelectric properties and speaker characteristics. The method of preparing a lead-free piezoelectric ceramic includes preparing a mixture in which copper oxide is added to a BCTZ-based base material and sintering the mixture at a temperature of 1300° C. to 1600° C. for 1 to 5 hours, wherein a weight ratio of the copper oxide in the mixture is 0.6 wt %.
