PURPOSE:To provide a dielectric ceramic composition of high permittivity, large no-load Q, and of small temperature variation of resonance frequency. CONSTITUTION:A dielectric ceramic composition comprises barium, neodymium, samarium, bismuth, titanium and oxygen. The composition formula is Ba(Nd1-x-ySmxBiy)2+ATi4+BO12+3A/2+2B, (where 0<=x<=0.8, 0.2<=y<=0.5, -0.5<=A<=+0.5, -0.5<=B<=+0.5, and 0.2<=x+y<=1). |
