DIELECTRIC COMPOSITION FOR MULTILAYER CERAMIC CONDENSER, MULTILAYER CERAMIC CONDENSER, AND METHOD FOR MANUFACTURING MULTILAYER CERAMIC CONDENSER

摘要

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 BaTiO3, MgCO3, Y2O3, Cr2O3, Mn2V2O7, and xBaO-yZrO2-zSiO2 acting 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 aBaTiO3-bMgCO3-cY2O3-dCr2O3-e(Mn2V2O7)-f(xBaO-yZrO2-zSiO2), 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 mum 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.
