| description | The invention discloses a preparation method of barium strontium titanate based aluminum oxide composite ceramic with high energy storage density. According to the method, firstly, raw materials, BaCO3, SrCO3 and TiO2 are prepared according to the chemical formula Ba0.4Sr0.6TiO 3, then ground, dried, sieved and calcined for 3 hours at the temperature of 1,150 DEG C, and Ba0.4Sr0.6TiO 3 powder is prepared; secondarily, the Ba0.4Sr0.6TiO 3 powder and Al2O3 powder are prepared in the mass ratio being (100-x):x, wherein x ranges from 1 to 5, the powder is ground, dried and sieved, and ceramic powder is prepared; the ceramic powder is put in a mold and sintered in a vacuum environment at the temperature of 1,000 DEG C through a discharge plasma sintering system, and a ceramic sintered body is prepared; the ceramic sintered body is subjected to thermal treatment for 3 hours at the temperature of 1,100 DEG C in the air atmosphere, and the barium strontium titanate based aluminum oxide composite ceramic with high energy storage density is prepared. The dielectric breakdown strength of the prepared composite ceramic can reach 300 kV/cm at the room temperature, and the energy storage density can reach 1.69 J/cm at the room temperature. The prepared barium strontium titanate based aluminum oxide composite ceramic with high energy storage density can be used for components such as a high-density energy storage capacitor and the like and has great application value in the high-power and impulse-power fields. |
