Barium strontium titanate composited zinc gallate ceramic material with high adjustable rate and low loss

The invention discloses a barium strontium titanate composited zinc gallate ceramic dielectric material with the high adjustable rate and low loss. The barium strontium titanate composited zinc gallate ceramic dielectric material with the high adjustable rate and low loss is characterized in that the component general formula is (1-x)Ba0.4Sr0.6TiO3-xZnGa2O4, wherein the value range of x is that xis larger than or equal to 10wt% and smaller than or equal to 70wt%; and BaTiO3 powder, SrTiO3 powder, ZnO powder and Ga2O3 powder are selected as main raw materials and matched according to (1-x)Ba0.4Sr0.6TiO3-xZnGa2O4, ball grinding, drying and high temperature pre-burning are conducted, mixed powder is prepared, the mixed powder is tableted, then subjected to rubber discharging at the temperature of 550-600 DEG C, and then fired at the temperature of 1250-1300 DEG C, and then the barium strontium titanate composited zinc gallate ceramic dielectric material is prepared. The prepared barium strontium titanate composi
