发明名称 Dielectric ceramic composition and multi-layer ceramic capacitor
摘要 The present invention provides a dielectric ceramic composition, which is, in addition to having superior resistance to reduction during firing, superior capacitance temperature characteristics after firing and superior dielectric characteristics, also demonstrates an enhanced lifetime for insulation resistance. The present invention is a dielectric ceramic composition comprising 0.18 to 0.5 part by weight of Yb2O3, 0.6 to 1.5 parts by weight of MgO, 0.4 to 1.5 parts by weight of CaSiO3, 0.02 to 0.2 part by weight of WO3, 0.1 to 0.4 part by weight of MnCO3 and 0.02 to 0.2 part by weight of MoO3 based on 100 parts by weight of (BaO)m.TiO2 (wherein, m is from 0.990 to 0.995).
