Structure ceramics being a low mechanical hysteresis and dielectric insulating material, a pressure transducer cut down creep, and increased reaction speed.
Near the transition temperature, a thermal hysteresis was found in dielectric, pyroelectric and piezoelectric measurements. Thus the transition should be of the first order transition.
在相变温度区域里,介电、热电和压电都有明显的热滞效应,具有一级相变特性。

The thermal hysteresis of the transition is about 70k, in agreement with that obtained from the dielectric and pyroelectric measurements.
