Abstract
Dielectric, piezoelectric and pyroelectric properties of 0.65(Pb/sub 1-x/Sr/sub x/)(Mg/sub 1/3/Ta/sub 2/3/)O/sub 3/-0.35PbTiO/sub 3/ (0/spl les/x/spl les/0.12) solid solution near the morphotropic phase boundary (PMT-PT) have been investigated. Dielectric constant and loss of poled ceramic samples were determined. The electromechanical coupling factor and piezoelectric d/sub 33/ constant were measured for various compositions in the ceramics. The pyroelectric coefficient and spontaneous polarization were measured by the static Byer-Roundy method as a function of temperature. The values of dielectric constant, piezoelectric d/sub 33/ constant and pyroelectric coefficient for Sr-doped PMT-PT are larger compared to the values observed for undoped PMT-PT ceramics. Transition temperature is continuously shifted to lower temperature with increase of a small amount of SrCO/sub 3/.
