摘要

Two new polycrystalline layered oxides Bi_(2.33)Ca_(0.17)Nb_(1.33)W_(0.17)O_(7.5) and Bi_(2.25)Ca_(0.25)Nb_(1.25)W_(0.25)O_(7.5), in which the number of perovskite layers is equal to 1. 5, have been synthesized. It has been revealed using X-ray powder diffraction analysis that both compounds have a single-phase composition and exhibit a structure of Aurivillius phases with orthorhombic unit cells corresponding to space group Cmm2. The analysis of the temperature dependences of the permittivity in the frequency range from 1 kHz to 1 MHz has demonstrated that these compounds are characterized by relaxor properties. This manifests itself in the frequency dispersion of the ferroelectric-paraelectric transition temperature and high values of the diffusivity parameter: γ = 1.75 and 1.82.
