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

SUNG TAE-HYUN / KIM KYUNG BUM

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 %.
