Abstract:
    A semiconductive ceramic composition for a reduction reoxidation type semiconductive ceramic capacitor capable of increasing capacitor, dielectric strength of the capacitor and improving temperature characteristics of the capacitor. The composition includes a BaTiO3 base component and a minor component consisting of Nb and Ce. Nb and Ce are present in amounts of 0.2 to 3.0 mol% on Nb2O5 and CeO2 bases. Addition of Co and the like increases insulation resistance and D.C. breakdown voltage of the capacitor and further improves temperature characteristics of the capacitor.
