Piezoelectric and strain characteristics of PMN-PT-PZ ceramics with Ba addition
Ba치환된 $Pb(Mg_{1/3}Nb_{2/3})O_3$ -$PbTiO_3$ -$PbZrO_3$ 계 세라믹스의 압전 및 변위특성에 관한 연구
Abstract
In this study, piezoelectric actuator samples were fabricated using 0.375PMN-0.37OPT-0.255PZ system ceramics with Barium substitution and the strain properties of them were investigated. Dielectric constant of the specimens increased with the increase of Ba content up to 5mol% and decreased with futher addition of Ba. The largest piezoelectric coefficient and electromechanical coupling coefficient were observed at the sintering temperature of 1250'C and Barium content of 5mol%. The characteristics of strain hysteresis was found largely with varing the sintering temperature on the single round type, and the strain is proportional to piezoelectric coefficient.
