: (1- x )BaTiO 3 - x ZnNb 2 O 6 ( x =0.5mol%, 1mol%, 1.5mol%, 2mol%, 3mol%, 4mol%) (BTZN) ceramics were synthesized by solid state method. The sintering temperature, structure, dielectric property and ferroelectric property of BTZN ceramics were systematically investigated. The sintering temperature of BTZN ceramics decreased with increasing ZnNb 2 O 6 content. XRD results show that the second phase Ba 2 Ti 5 O 12 was observed when the content of ZnNb 2 O 6 reached 3mol%. The dielectric measurements result showed that with increasing ZnNb 2 O 6 content, the dielectric constant of BTZN ceramics decreased gradually, while the frequency stability of dielectric constant increased gradually. The temperature dependence of dielectric constant results showed that all BTZN ceramics met the charac-teristics of X8R capacitors. The polarization values of BTZN ceramics decreased with increasing ZnNb 2 O 6 content. Recoverable energy density of 1.22 J/cm 3 and Energy storage efficiency of 77.6% were achieved at 240 kV/cm for the sam-ple with x =4mol% .
