专利汇可以提供Highly dielectric ceramic compound专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide a ceramic compound, which can be baked even under neutral/reductive atmosphere by adding a specified amount of PbO and NiO to a provisionally baked powder of dielectric ceramic compound as main component to be expressed as specified.
CONSTITUTION: As bi-components, 1.0-25.0mol% PbO and 1.0-15.0mol% NiO are added to a provisionally baked powder of dielectric ceramic compound as main component, which is expressed by Eq. I, wherein x shall range as 0.35≤x≤0.7. This addition of PbO and NiO to the baking of Eq. I series powder in pevroskite structure will generate liquid phase at a low temp. through utilization of cocrystallization composition with PbO and NiO, and solid solution of these additives allows smooth diffusion into dielectric substance, wherein suppression of grain boundary layers to be formed due to additives prevents drop of the dielectric factor, and thus a large capacity laminate ceramic capacitor or thick-film capacitor is obtained, which can be densely baked in a short time at a low baking tamp. of 1000°C or lower.
