Barium titanate ceramic dielectric material and capacitor prepared using barium titanate ceramic dielectric material
The invention relates to the technical field of ceramic dielectric materials and components and parts prepared using the ceramic dielectric materials, in particular to a barium titanate ceramic dielectric material and a high voltage chip-type multilayer capacitor prepared using the barium titanate ceramic dielectric material, wherein the barium titanate ceramic dielectric material is prepared through the following method steps: A, calcining: calcining BaTiO3 powder with the initial particle size D50 being equal to 0.1-0.3 [mu]m for 2-3 hours at the temperature of 1100-1200 DEG C, the particle size D50 of calcined BaTiO3 powder is controlled to be equal to 0.8-1.5 [mu]m; B, doping, doping powder in the step A with oxide, the weight of oxide accounts for 4-8% of the total weight of powder in the step A; C, performing mixed dispersion on the powder in the step B through wet ball grinding, and further drying. The multilayer capacitor prepared using the barium titanate ceramic dielectric material has a nominal voltage of 10000V, uses a nickel electrode as the inner electrode, can realize low-cost base metallization of high voltage products, and can be extensively applied to civilian electronic products with low cost requirements.
