摘要：

Dielectric, pyroelectric and piezoelectric properties of the solid solution: (1-x) Pb(In1/2Ta1/2)O-3 - (x) PbTiO3 [PIT: PT] have been investigated. High dielectric constant of 2300 at room temperature and 13000 at approximately 248 degrees C, remnant polarization of approximately 26 mu C/cm(2), and coercive field of 11 kV/cm were measured for compositions near the morphotropic phase boundary [MPB] at x = 38 mol% PT Poled ceramics of this composition gave a piezoelectric coefficient, d(33), of 302 pC/N and piezoelectric coupling coefficients, k(p) and k(31), of 37% and 20%, respectively.
