Nonreducing dielectric ceramic and monolithic ceramic capacitor using the same

摘要

A nonreducing dielectric contains a main-component having a perovskite crystal phase and satisfying the formulaand a compound oxide represented by the formulae (Si, T)O2-MO-XO and (Si, T)O2-(Mn, M')O-Al2O3. The ratio of the intensity of the maximum peak of a crystal phase not of the perovskite crystal phase to the intensity of the maximum peak assigned to the perovskite crystal phase appearing at 2theta=25 to 35° is about 5% or less in a CuKalpha X-ray diffraction pattern.
