Abstract:
1. A dielectric ceramic composition comprising: a base powder represented by (1−a)[(1−x)BaTiO 3 −xBi(Mg 0.5 Ti 0.5 )O 3 ]+a[(1−y)BaTiO 3 −yBi(Mg 0.5 Ti 0.5 )O 3 ](wherein x, y, and a satisfy 0≦x≦0.05, 0.05≦y≦0.5, a≧0, and 0.01−x≦a≦1−y) and including a first powder represented by [(1−x)BaTiO 3 −xBi(Mg 0.5 Ti 0.5 )O 3 ] and a second powder represented by [(1−y)BaTiO 3 −yBi(Mg 0.5 Ti 0.5 )O 3 ], each of the first powder and the second powder containing a first main component represented by BaTiO 3 and a second main component represented by Bi(Mg 0.5 Ti 0.5 )O 3 , but at different ratios.
