摘要

This paper describes the preparation and properties of (Na0.5Bi0.5)(1-x)A(x)TiO(3) (A = Sr, Cd) lead-free ferroelectric ceramics. The (0.63-0.66) Na0.5Bi0.5TiO3 center dot (0.37-0.34)Sr0.7Bi0.2TiO3 ceramics are shown to have the best dielectric and piezoelectric properties: tan delta = 0.013-0.009, epsilon(RT) = 1200-1500, d(31) = (370-400) x 10(-12) C/N, and k(rho) = 0.4-0.58. The cadmium-containing ceramics offer low dielectric losses and high dielectric permittivity at room temperature.
