What is Degradation of PZT-4D hard piezoceramics under moderate heating about?
The changes produced in the dielectric permittivity, the transverse piezoelectric coecient, the k 31 coupling factor, the s 11 E elastic compliance and the mechanical quality factor of PZT-4D hard piezoceramics by heating have been investigated. The ceramics were then repoled, and the reversible and irreversible components of the changes quanti®ed. The results showed that depolarisation began at 150 C. A high level of poling was retained even after heating at 300 C (d 31 =À8310 À12 C N À1 and k 31 =0.225), only 20 C below the transition temperature. However, a signi®cant irreversible degradation of the mechanical quality factor, Q m , occurred at a temperature as low as 100 C. Experiments on thinned specimens showed that the degradation of Q m took place in the Ag doped layer produced by the electrodes. Indentation surface cracks were also introduced into the ceramics to investigate the behaviour of cracks during the thermal treatments.
