摘要：

(1-x)(0.96　Bi0.5Na0.5TiO3-　0.04BaTiO3)-　xBi(Zn0.5Ti0.5)O3　ceramics　were　synthesized　using　conventional　solid　oxide　reaction　routes.　The　phase　structure　and　relaxor　characteristics　of　the　ceramics　were　characterized　by　X-ray　diffraction　and　temperature-dependence　dielectric　response.　The　results　show　that　the　perovskite　structure　keeps　stable　for　Bi(Zn0.5Ti0.5)O3　addition　x≤0.05.Besides,　with　Bi(Zn0.5Ti0.5)O3　addition　increasing,　the　phase　structure　transformed　from　the　rhombohedral-　tetragonal　coexistence　to　pseudo-cubic　phase,　and　the　diffusive　factor　increased　while　the　activation　energy　for　dipole　freezing　decreased.　These　indicate　that　Bi(Zn0.5Ti0.5)O3　addition　significantly　enhance　the　relaxor　be-haviour　of　0.96Bi0.5Na0.5TiO3-　0.04BaTiO3　ferroelectric　ceramics.
