Ceramic Composition for Piezoelectric Actuators with Excellent Temperature Characteristics

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceramic composition for piezoelectric actuators having a large displacement and an excellent temperature characteristic.;The ceramic composition for a piezoelectric actuator of the present invention is based on Pb (Zr _0.53 , Ti _0.47 ) O ₃ , and based on the total weight of the composition, 0.5% to 1.5% by weight of Nb ₂ O ₅ and 0.04% by weight of MnO _2. To 0.22% by weight.
