Preparation method of barium-strontium-titanate-based glass composite ceramic with high energy storage density
The invention discloses a preparation method of barium-strontium-titanate-based glass composite ceramic with a high energy storage density. The method comprises the following steps: firstly mixing BaCO3, SrCO3 and TiO2 which are used as raw materials according to a chemical formula Ba0.4Sr0.6TiO3 to prepare Ba0.4Sr0.6TiO3 powder; secondly mixing SiO2, Al2O3, B2O3, ZnO and K2O which are used as the raw materials according to a mass ratio of 57 to 17 to 15 to 9 to 2, preparing glass, grinding the glass to prepare glass powder; then mixing Ba0.4Sr0.6TiO3 powder with the glass powder according to a mass ratio of (100-x) to x, and preparing ceramic powder; and finally filling the ceramic powder in a die, sintering the die at the temperature of 1000 DEG C in the vacuum environment by using a discharge plasma sintering system to prepare a ceramic sintered body, and carrying out heat treatment to prepare the barium-strontium-titanate-based glass composite ceramic with the high energy storage density. According to the barium-strontium-titanate-based glass composite ceramic with the high energy storage density prepared by the method, the energy storage density and the dielectric breakdown field intensity are greatly improved; the barium-strontium-titanate-based glass composite ceramic can be applied to components such as high-density energy storage capacitors, and has high application value in the fields of high power and pulse power.
