압전 액츄에이터용 PSN-PZT 세라믹스의 압전 특성에 미치는 MnO2 첨가 효과

The effect of $MnO_{2}$ as a sintering additive on the microstructures and the piezoelectric properties, especially mechanical quality factor, of 0.05 Pb $(Sb_{0.5}Nb_{0.5})O_{3}$ -0.95 Pb $(Zr_{0.52}Ti_{0.48})O_{3}$ (PSN-PZT) piezoelectric ceramics was investigated. The samples were sintered ...
