Dotierte Titanatglaskeramik für Kondensatoren mit Korngrenzensperrschichten.
摘要
A high dielectric constant glass-ceramic material comprising small conducting grains based on BaTiO3 and/or SrTiO3 on the order of about 0.5-10.0 mu m surrounded by a thin microcrystalline insulating barrier layer at the grain boundary about 0.01-0.10 mu m thick wherein the conductivity of the grains is enhanced by addition of about 0.1-4.0 mol% of a dopant selected from among Group V elements, Ge and Si substantially incorporated in the bulk lattice of the grains upon Ti sites. A novel process for forming the glass-ceramic material is also disclosed.
