Dielectric ceramic composition, ceramic capacitor using the composition and method of producing thereof

Abstract

The present invention provides a dielectric ceramic composition, a capacitor using the composition and the producing method, of having a lower dielectric loss and a stable characteristics in high frequency bandwidth, and enabling to use a base metal or a carbon-based material as an electrode material by allowing sintering at a low temperature, thereby resulting in lower cost. The dielectric ceramic composition according to present invention, is characterized in comprising a main component of formula SrxMg1-x(ZryTi1-y)O3 (where 0.8≦x≦1; 0.9≦y≦1) to which MnO2 of 0.05-15 wt %, at least one of 0.001-5 wt % selected from the group consisting of Bi2O3, PbO and Sb2O3 and a glass component of 0.5-15 wt % are added based on the weight of the main component.
