PURPOSE:To provide a ceramic compound for reduction reoxidization semiconductor condenser so that its capacity per unit area is 0.60muF/cm<2> or more its insulation resistance is 10<10>OMEGA or more, its breakdown voltage is 700V or more, and its tandelta is less than 2.0. CONSTITUTION:A ceramic compound which contains BaTiO3 (a part can be substituted by SrTiO3 or BaZrO3) and Bi2O3 ; TiO2 or ZrO2 ; and at least one kind of oxide selected from the group consisting of La, Ce, Nb, Nd, Dy, Y, Sb, W, Ta and the group consisting of Cr, Fe, Co, Zn, Cu, Al, Mg, Si. A reduction reoxidization type semiconductor ceramic condenser, which exhibits new characteristics not present in the past, can be produced. |
