<P>PROBLEM TO BE SOLVED: To provide a reduction-resistant dielectric composition prepared by uniformly dispersing a sintering additive component into a main component without segregation and a ceramic electronic component using the reduction-resistant dielectric composition, having excellent reliable durability, small self-heating in high frequency current and excellent charcteristics for medium/high voltage. <P>SOLUTION: The reduction-resistant dielectric composition is obtained by successively carrying out a process for preparing a colloidal suspension containing the sintering additive component expressed by general formula, (Ca<SB>1-X</SB>Ba<SB>X</SB>)SiO<SB>3</SB>(where 0≤X≤1) by dropping ammonia water while stirring and mixing acetate aqueous solution of at least one or more kinds of Ca and Ba with a metal alkoxide ethanol solution of Si and a process for preparing raw material powder by mixing the colloidal suspension with powder of a main component expressed by general formula, (Sr<SB>1-X</SB>Ca<SB>X</SB>)<SB>m</SB>(Ti<SB>1-Y</SB>Zr<SB>Y</SB>)O<SB>2+m</SB>(where 0.55≤X≤0.85, 0.80≤Y≤1.00 and 993≤m≤1,007) and a trace quantity of an additive. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
