<P>PROBLEM TO BE SOLVED: To provide a nonreducing dielectric porcelain composition for temperature compensation, which can be stably fired even under a reducing atmosphere of 1,100-1,300°C, gives markedly increased Q value, and is small in dispersion of the characteristic such as capacitance Cap, dielectric constant ε<SB>s</SB>, temperature characteristic TC or insulating resistance ρ, and which is able to prevent flocculation of glass components. <P>SOLUTION: The dielectric composition contains 1-5 pts. wt. of MnCO<SB>3</SB>, and 0.5-5 pts. wt. of a glass component expressed by general formula: aSiO<SB>2</SB>-bLi<SB>2</SB>O-cB<SB>2</SB>O<SB>3</SB>-dCaO-eBaO (wherein, 0.25≤a≤0.45; 0.05≤b≤0.35; 0.05≤c≤0.15; 0.10≤d≤0.35; 0.10≤e≤0.35, and a + b + c + d + e =1) to 100 pts. wt. of a base component expressed by general formula: (CaO)<SB>x</SB>(Zr<SB>1-y</SB>-Ti<SB>y</SB>)O<SB>2</SB>(wherein, 0.95≤x≤1.05; and 0.01≤y≤0.10). <P>COPYRIGHT: (C)2004,JPO |
