PSN-PT 세라믹스의 진동레벨 특성

초록

In this paper, High quality factor and fine dielectric loss was resulted on specimen added 0.5wt% MnO2 after compared and analyzed dielectric and piezoelectric properties following that added each 0-0.9wt% of Fe2O3. Nb2O5, and MnO2 on dopant at PSN-PT in two material disposition ceramics with research still is not complered to material investigation to increase high power piezoelectric actuator device efficiency. And, a measuring methode and the experimental results of the temperature rise under the high vibrational velocity are also described.
