【Abstract】 A series of Ba1－ xSrxTi1－ yMyO3 (M=Zr,Sn, 0≤ x≤ 0.5,0≤ y≤ 0.3) solid solutions were synthesized by chemical method at below 100℃ . XRD and cell parameters component figures of the series of the solid solutions powder demonstrated that the compounds are mutually miscible in the solid solutions. The particls size is about 70nm with spherical shape and uniform distribution. The result of preparing ceramics showed that after adulterating with Sr2＋ and Zr4＋ or Sn4＋ in pure BaTiO3 phase, the dielectric constant increased eight times while the dielectric loss decreased three times at room temperature.更多还原
