Abstract：(1-x)BaTiO3-xBi(Mg2/3Sb1/3)O3(x=0,0.08,0.12,0.16)(BT-xBMS)ceramics were pre-pared by solid phase method.The effects of BMS content on the microstructure,structure,dielectric and ferroelectric properties of BT-based ceramics were systematically investigated.The results indicate that BT-xBMS ceramics have a single perovskite structure.With the increase of BMS content,the BT-xBMS ceramics exhibit a refined grain size and transform from normal ferroelectrics to relaxor ferroelectrics.In addition,the residual polarization of BT-xBMS ceramics is significantly reduced,which contributes to ob-taining excellent energy storage performance.When x=0.12,high recyclable energy storage density(Wrec=3.06 J·cm-3)and energy storage efficiency(η=94.02%)can be obtained at 460 kV·cm-1,which indicates that the BT-xBMS ceramics have great development potential in the field of dielectric capacitors.
