Dielectric ceramic composition multilayer ceramic capacitor including the dielectric ceramic composition and method for fabricating the multilayer ceramic capacitor
The present invention provides a multilayer ceramic capacitor which can simultaneously realize all properties of target properties such as a plasticity temperature of 1100°C or less, a dielectric constant of 3500 or more and high temperature withstand voltage of 50 V/μm or more. A dielectric magnetic composition comprises: a barium titanate powder included as a main component; a first subcomponent including sodium (Na); a second subcomponent including barium (Ba); and a third subcomponent including silicon (Si). The content of the first subcomponent is included in a range of 0.3 to 4.0 mole based on Na element per 100 mole of the main component. A ratio of Ba/Si satisfies 0.16 to 1.44.
본 발명은 주성분으로 포함되는 티탄산바륨계 분말; Na를 포함하는 제1 부성분; Ba를 포함하는 제2 부성분; 및 Si를 포함하는 제3 부성분;을 포함하고, 상기 제1 부성분의 함량은 주성분 100 mole당 Na 원소 기준으로 0.3 내지 4.0 mole 범위에 포함되고, Ba/Si 비율은 0.16 내지 1.44를 만족하는 유전체 자기 조성물에 관한 것이다.
