PSN-PT 세라믹스의 진동레벨 특성

Characteristics of vibrational level to PSN-PT ceramics

In this paper, High quality factor and fine dielectric loss was resulted on specimen added 0.5wt% $MnO_2$ after compared and analyzed dielectric and piezoelectric properties following that added each 0 $\sim$ 0.9wt% of $Fe_2O_3$, $Nb_2O_5$, and $MnO_2$ on dopant at PSN-PT in two material disposition ceramics with research still is not completed to material investigation to increase high power piezoelectric actuator device efficiency. And, a measuring method and the experimental results of the temperature rise under the high vibrational velocity are also described.
