    摘要: PURPOSE: A non-reducible low temperature sintering dielectric ceramic composition for a multi layer ceramic capacitor is provided to prevent the reliability deterioration by the reduction of the dielectric thickness by the high capacity through mixing a main component with a secondary main component. CONSTITUTION: A non-reducible low temperature sintering dielectric ceramic composition for a multi layer ceramic capacitor (10) contains 91-98 wt% of first component and 2-9 wt% of second component. The first component contains 94-98 wt% of BaTiO3 which is a main component, 0.5-2 wt% of first secondary component, and 1-4 wt% of second secondary component. The first secondary component is glass powder having a network structure, and the second secondary component is formed of more than one compound selected from MgO, Cr2O3, or Mn3O4. The second secondary component is denoted by (Ba1-x-yCaySrx)(ZryTi1-y)O3, and x and y satisfy 0.2
