摘要：<p>A dielectric ceramic composition, comprising a sintered mixture of a neodymium- and lanthanide-substituted barium titanate dielectric ceramic and a barium, silicon and boron oxide glass, is new. A novel dielectric ceramic composition comprises a sintered mixture of a dielectric ceramic component of formula BaO-TiO2-(Nd1-mMem)O3/2 (Me = a lanthanide and m = 0 to 1.0) and a glass component comprising barium, silicon and boron oxides. An Independent claim is also included for a multilayer ceramic substrate comprising a low temperature sintered, low dielectric constant insulating ceramic layer and a high dielectric constant dielectric ceramic layer consisting of the above dielectric ceramic composition. Preferred Features: The glass component has the composition 20.0-65.0 mol% barium oxide, 5.0-50.0 mol% silicon oxide and 10.0-50.0 mol% boron oxide.</p>
