概要
- 論文の詳細を見る
Vibration-level characteristics for Fe-doped lead-zirconate-titanate ceramic were studied using the constant current driving method. It was found that mechanical Q was markedly decreased with increasing vibration level, accompanying a lot of heat generation. The other electromechanical characteristics were slightly changed. The heat generation was found to decrease with increasing Fe doping concentration up to 〜2 at. %, and was found to show a minimum for lead-zirconate-titanate with the basic composition close to the morphotrophic phase boundary. It was assumed that the heat generation was mainly caused by ferroelectric domain wall hysteresis loss.
