Abstract
Dielectric, piezoelectric and pyroelectric response of selected compositions from the solid solution system have been investigated as a function of PT and PZ content for composition near the morphotropic phase boundary (PMT-PT). The dielectric constant and loss of poled samples were determined. The piezoelectric d33 constant and electromechanical coupling factor were measured for various composition in the system. The pyroelectric coefficient and spontaneous polarization were measured by the static Byer-Roundy method as a function of temperature. The stability of the perovskite phase was studied as a function of sintering temperature. The transition temperature of the ceramics decreased gradually with the addition of PZ
