Non-reducible dielectric ceramic composition
Abstract
Abstract A non-reducible dielectric ceramic composition consists essentially of a main component consisting essentially of oxides of BaO, CaO, MgO, TiO 2 , ZrO 2 and Nb 2 O 5 and having a composition expressd by the general formula: {(Ba.sub.1-x-y Ca.sub.x Mg.sub.y)O}.sub.m (Ti.sub.1-o-p Zr.sub.o Nb p )O 2+p/2 wherein 0<x≦0.20, 0<y≦0.05, 0<o≦0.25, 0.0005≦p ≦0.023, and 1.000≦m≦1.03; at least one primary additive selected from the group consisting of oxides of Mn, Fe, Cr, Co and Ni; and at least one secondary additive selected from the group consisting of SiO 2 and ZnO. The primary additives contained in an mount of 0.02 to 2.0 moles per 100 moles of the main component in terms of respective oxides, MnO 2 , Fe 2 O 3 , Cr 2 O 3 , CoO and NiO, while the secondary additive is contained in an amount of 0.1 to 2.0 moles per 100 moles of the main component.
