Barium titanate based composite capacitor ceramic material and preparation method thereof
The invention discloses a barium titanate based composite capacitor ceramic material and a preparation method thereof. The ceramic material comprises 4-10 parts of barium titanate, 3-8 parts of calcium zirconate, 2-6 parts of magnesium titanate, 10 copies, 4-10 parts of titanium dioxide, 3-7 parts of calcium titanate, 2-6 parts of aluminum zirconate, and 3-6 parts of strontium zirconate. The preparation method comprises the steps of: (1) subjecting the components to ball milling in a ball mill; (2) stirring the ceramic material powder obtained in step (1) uniformly, then adding polyvinyl alcohol and further performing stirring for 30-60min; (3) pressing the powder material of step (2) into a green body at a compression pressure of 40-70MPa for 3-5h; and (4) subjecting the green body of step (3) to high temperature sintering in a high temperature sintering furnace, and then performing cooling to obtain the barium titanate based composite capacitor ceramic material. The prepared composite capacitor ceramic material has the excellent performance of high compression strength and high breakdown resistance.
