Abstract: Ba_0.85Ca_0.15Zr_0.1Ti_0.9O₃ （BCZT） powder was prepared by a modified sol‑gel method and traditional solid phase method， respectively. BCZT ceramics were prepared by a solid state reaction process at different sintering temperatures. The reaction process and structure of sol⁃gel powder were tested by X‑ray diffraction， FT‑IR spectrometer and thermal analyzer. The sintering process of ceramic was investigated by a high temperature image sintering instrument. The results showed that the best calcination temperature of BCZT powder prepared by sol⁃gel method was 900 ^oC， the best sintering temperature of ceramic was 1400 ^oC； While the best sintering temperature of ceramic prepared by solid phase method was 1500 ^oC. The electrical property analysis showed that the relative permittivity and the remnant polarization of ceramics prepared by sol‑gel method were 11 082.5 and 9.80 μC/cm²， respectively. The electrical properties of BCZT ceramics prepared by sol‑gel process were greatly improved compared with those prepared by solid phase method.
