Abstract
The invention provides a doped modified SrZrO3-based middle-high voltage ceramic capacitor material, in particular to a middle-high voltage ceramic capacitor material doped with modified SrZrO3 and prepared from the following components in percentage by weight: 60-64 percent of SrZrO3, 20-24 percent of SrTiO3, 4-8 percent of MnO2, 8-10 percent of Dy2O3 and 8-12 percent of CaZrO3. The sum of each component is 100 percentage. The SrZrO3, the SrTiO3, the MnO2, the Dy2O3 and the CaZrO3 are mixed according to a formula ratio and polyvinyl alcohol is added to press and mold. The middle-high voltage ceramic capacitor material doped with modified SrZrO3 is obtained by sintering in a temperature range between 1250 DEG C to 1400 DEG C. By adopting the prescription, the dielectric constant of the economical middle-high voltage ceramic capacitor material doped with modified SrZrO3 can be increased to 12,800, the withstand voltage is increased to 19KV/mm and the temperature characteristics is Y5U.
