摘要：
A dielectric ceramic composition is formed of a mixture including a BaO--TiO.sub.2 --REO.sub.3/2 ceramic composition, wherein RE represents a rare earth element, and a glass composition containing about 13-50 wt. % SiO.sub.2, about 3-30 wt. % B.sub.2 O.sub.3, about 40-80 wt. % alkaline earth metal oxide and about 0.5-10 wt. % Li.sub.2 O. The dielectric ceramic composition has a high dielectric constant and a high Q value, as well as excellent temperature stability, and is capable of being sintered at a relatively low temperature. The dielectric ceramic composition is advantageously used in ceramic electronic parts.
