Abstract
Disclosed herein are a multilayer ceramic capacitor, a dielectric composition capable of sintering at a lower temperature and having a small variation in dielectric constant, a multilayer ceramic capacitor using the same, and a method thereof. The dielectric composition includes BaTiO, MgCO, YO, CrO, MnVO, and xBaO-yZrO-zSiOacting as a sintering agent (where 0.1≦x≦0.3, 0.1≦y≦0.3 and 0.4≦z≦0.8, x+y+z=1), wherein when representing the composition with the formula aBaTiO-bMgCO-cYO-dCrO-e(MnVO)-f(xBaO-yZrO-zSiO), the ratio of the components satisfies the conditions of a=100, 0.1≦b≦3.0, 0.3≦c≦2.0, 0.05≦d≦0.2, 0.01≦e≦1.5, 0.5≦f≦3.0 based on the molar ratio. When manufacturing a multilayer ceramic capacitor of a higher capacitance, which is formed to have the thin layer structure of 4 μm or less, short circuits between internal electrodes and the deterioration in capacitance due to massing of the electrodes into ball at the ends may be remarkably reduced.
