Phase transitions in PbZrxTi₁_XO₃ with up to 3% Ti content

On the basis of investigations of dielectric, pyroelectric and piezoelectric properties and by differential thermal analysis, the existence of a ferroelectric phase and of A ↔ F and F ↔ P phase transitions in Pb/Zr x Ti1-x /O3 samples, containing up to 3% Ti, were determined. It has been shown that a ferroelectric state appears despite the lack of doping and despite the lack of external factors. The introduction of Ti causes a lowering of the energy barrier between the A and F states. The results verify a cluster mechanism for the appearance of an F state in the antiferroelectric PbZrO3 matrix.
