Effect of the Sintering Temperature on the Formation of Ferroelectric Properties of a Lead Zirconate–Titanate Ceramic

Аннотация

Effect of the sintering temperature on the formation of the microstructure, the domain structure, and the ferroelectric properties of a lead zirconate–titanate Pb(Ti_xZr_{1 – x})O₃ piezoelectric ceramics has been studied. It is shown that the ferroelectric phase forms at a sintering temperature of 860°C. At higher sintering temperatures, the main effect on the properties is due to a unit cell deformation and free charge carriers.
