摘要：
We have studied the deformation, polarization, and reversible characteristics of [(Na0.5K0.5)1 − xLix](Nb1 − y − zTaySbz)O3 ceramics, and examined the effect of an applied electric field on their properties. Property-structure-composition relationships have been inferred, and the influence of CuO + TiO2, CaO, CdO, and SrO + TiO2 additions has been assessed. The results are interpreted in terms of the defect structure of the ceramics and domain wall mobility. The most attractive materials for microwave applications and dielectric amplifiers are identified.
