　　The Sr0.97Sm0.02TiO3(SSTO)ceramics were prepared by solid state reaction method with relative dielectric constant 3681 and a low dielectric loss~0.02(at 1 kHz and room temperature).In order to improve the performance stability under the bias field,ZrO2 is added to the SSTO ceramics.Experimental results show that the comprehensive dielectric properties for the sample with 1 wt%ZrO2 is best among all the composition with the variation of dielectric loss from 30%to 7%at the 0-20 kV/cm.
