Abstract: A barium titanate host material (Ba.sub.x Ca.sub.y), (Ti.sub.z Sn.sub.w)O.sub.3 including a small amount of PbO (approximately 0-2.0 wt. %) is doped with small amounts of a lead boro alumino silicate frit, and one or more of boric acid and the oxides of La, Zn, Cu, Nb, Mn and Y, thereby resulting in a dielectric ceramic composition particularly suitable for making low fired multilayered capacitors exhibiting Y5V characteristics and high dielectric constants in the range of 11,000 to 14,000.

Abstract: Ceramic dielectric compositions for manufacturing multilayer ceramic capacitors (MLCC's) having very high dielectric constants between about 8,000-19,000 and meeting the Z5U and Y5V EIA (Electronic Industries Association) specifications for temperature coefficient of capacitance, are prepared from barium titanate host materials based upon the formulation (Ba.sub.1-x Ca.sub.x) (Ti.sub.1-y-z Sn.sub.y Zr.sub.z)O.sub.3, and doped with small amounts of niobium, manganese, lanthanum, zirconium and yttrium oxides to alter the dielectric spectrum so as to meet desired EIA specifications.
