Abstract
A dielectric ceramic composition for multi-layer ceramic capacitor for use in extreme environments is formed by mixing a main compos it ion and a composite oxide for low-temperature sintering, where the main composition includes 96.0 to 99.0 wt. % of BaTiOand 1.0 to 4.0 wt. % of NbOand CoOas an additive. The main composition is formed by per forming a heat treatment for synthesis to form a core-shell structure having the BaTiOas a core and the NbOand CoOcovering the sur face of the BaTiO. The composite oxide for low-temperature sintering is at least one selected from BaVO, BaVOand BaVO.
