摘要：

The temperature coefficient of resonance frequency (TCF) of the piezoelectric Pb((ZrxTil-x)0.95(Mn1/3Nb2/3)0.05]O3ceramics is investigated by ways of the Zr/Ti ratio, additive, sintering and poling temperatures. The morphotropic phase boundary (MPB) locates at ϗ value near 0.51, where the planar electromechanical coupling factor (Kp) reaches a maximum with TCF value of approximately 0 ppm/°C. The ceramic composition exhibiting TCF value of 0 ppm/°C is changed with processing conditions and can be explained by the shift of the MPB compositions or the phase change. © 1990, Taylor & Francis Group, LLC.
