ABSTRACT:
A dielectric ceramic composition is disclosed which consists principally of barium oxide, titanium oxide, neodymium oxide, samarium oxide and bismuth oxide, which are represented by the following formula xBaO--yTiO.sub.2 --z[(1-a-b)Nd.sub.2 O.sub.3 --aSm.sub.2 O.sub.3 --bBi.sub.2 O.sub.3 ], where 0.10.ltoreq.x.ltoreq.0.20, 0.60.ltoreq.y.ltoreq.0.75, 0.10.ltoreq.z.ltoreq.0.24, x+y+z=1, 0<a.ltoreq.0.25 and 0<b.ltoreq.0.30. Also disclosed is a dielectric ceramic composition which consists principally of: barium oxide, titanium oxide, neodymium oxide, samarium oxide and bismuth oxide as major components which are represented by the following formula xBaO--yTiO.sub.2 --z[1-a-b)Nd.sub.2 O.sub.3 -aSm.sub.2 O.sub.3 --bBi.sub.2 O.sub.3 ], where 0.10.ltoreq.x.ltoreq.0.20, 0.60.ltoreq.y.ltoreq.0.75, 0.10.ltoreq.z.ltoreq.0.25, x+y+z=1, 0<a.ltoreq.0.30 and 0<b.ltoreq.0.35; and not more than 2.0 parts by weight of alumina per 100 parts by weight of a total of the major components.
