Abstract:
Disclosed are a glass composition and a dielectric composition enabling low temperature sintering, and a high capacitance multilayer ceramic capacitor using the same. In the glass composition used for sintering, the glass composition may be formed of a formula, aR2O-bCaO-cZnO-dBaO-eB2O3-fAl2O3-gSiO2, and the formula may satisfy a+b+c+d+e+f+g=100, 0≦a≦7, 1≦b≦3, 1≦c≦15, 10≦d≦20, 3≦e≦10, 0≦f≦3, and 55≦g≦72. Through this, when manufacturing the high capacity multilayer ceramic capacitor, the dielectric substance may enable the lower temperature sintering, thereby enhancing a capacitance and a reliability of the high capacitance multilayer ceramic capacitor.
