High-voltage ceramic pulse capacitor, dielectric material and preparation method of dielectric material
The invention discloses a high-voltage ceramic pulse capacitor, a dielectric material and a preparation method thereof. The dielectric material for the high-voltage ceramic pulse capacitor comprises the following raw materials in parts by weight: 100 parts of SrTiO3, 35 to 60 parts of SrZrO3, 10 to 20 parts of BiX, 0.05 to 2 parts of MnCO3, 0.4 to 2 parts of MgO, 0.5 to 3 parts of Zn2SiO4 and 0.5to 3.5 parts of BaB2O4, BiX is a compound formed by solid-phase synthesis of Bi2O3 and TiO2 or Bi2O3 and ZrO2, the specific composition of the dielectric material is limited, srTiO3 is used as a basis, by matching with SrZrO3, Zn2SiO4 and BiX, introducing Zn2SiO4 and limiting the addition amounts of SrTiO3, SrZrO3, Zn2SiO4 and BiX so as to limit the ratio of SrTiO3 to SrZrO3 to Zn2SiO4 to BiX andthe specific composition of BiX, the dielectric constant of the dielectric material is effectively controlled within the range of 250 +/-30, and the capacitance temperature coefficient is controlled within the range of -2500 to -1600 ppm/K while the loss is properly reduced, so that the prepared high-voltage ceramic pulse capacitor can be used for designing a high-voltage energy storage capacitorwithin the temperature range of -55 DEG C to 125 DEG C.
