Abstract:
A dielectric ceramic composition comprising:100 mol % of an oxide of Ba, Ti and Zr, the content of the oxide of the Ba, Ti and Zr being calculated by assuming that the oxide thereof is Ba(Ti1âˆ’xZrx)O3; 0.25 to 1.5 mol % of an oxide of Re, Re representing one or more elements selected from the group consisting of Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Y, the content of the oxide of the Re being calculated by assuming that the oxide thereof is Re2O3; 0.1 to 0.4 mol % of an oxide of Mg, the content of the oxide of the Mg being calculated by assuming that the oxide thereof is MgO; 0.03 to 0.6 mol % of oxides of one or more elements selected from the group consisting of Mn, V and Cr, the contents of the oxides of the Mn, V and Cr being calculated by assuming that the oxides thereof are Mn2O3, V2O5 and Cr2O3, respectively; 0.02 to 0.3 mol % of oxides of one or two elements of Mo and W, the contents of the oxides of Mo and W being calculated by assuming that the oxides thereof Mo3O3, WO3, respectively; and a glass component including SiO2, wherein x in the oxide of Ba(Ti1âˆ’xZrx)O3 ranges from about 0.05 to about 0.26.
