Dielectric ceramic composition and ceramic electronic component employing the same |
摘要 |
A dielectric ceramics includes a main ingredient, and a supplemental ingredient in an amount of 0.05 to 2 wt % for the main ingredient. The main ingredient is expressed by xBiO3/2-yCaO-zNbO5/2 and is within a scope of a specified quadrilateral region in a ternary system diagram, and the supplemental ingredient is a glass composition including at least SiO2, Li2O and MO (M includes at least one of Ca, Sr and Ba). A ceramic electronic component is produced by co-firing a dielectric layer composed of the dielectric ceramics and a conductive layer mainly composed of silver, and has a low degradation in Q value and excellent microwave characteristics.
