Abstract

This work investigated the in-situ temperature stability of 0.76(Bi0.5Na0.5)TiO3-0.04(Bi0.5Li0.5)TiO3-0.2(Bi0.5K0.5)TiO3 piezoceramics and a compression-mode accelerometer composed of these materials. The temperature-dependent charge sensitivity of the accelerometer was governed by the small-signal piezoelectric coefficient d33 rather than by the large-signal piezoelectric coefficient d∗33 of the (Bi,Na)TiO3-based ceramics. The significant decrease in the charge sensitivity in the vicinity of the depolarization temperature is closely related to the main intrinsic contribution to the piezoelectricity, i.e., the decrease in the crystal anisotropy associated with the temperature-induced polar ferroelectric-nonpolar relaxor phase transition.
