PURPOSE:To increase dielectric constant, voltage non-linearity index, surge withstand amount, etc., by incorporating a third element Ni3N2 in a voltage- dependent non-linear resistor ceramic composition consisting of the main element of a first element SrTiO3 and metal oxide of a second element. CONSTITUTION:A third element Ni3N2 of 0.001-5.000mol% is contained within a voltage-dependent non-linear resistor ceramic composition consisting of the main element of a first element of 90.000-99.998mol% and the metal oxide of a second element of 0.001-5.000mol%. The first element consists of at least one type out of Sr3TiO3, CaXSr1-XTiO3(0.001<=X<=0.5), BaySr1-YTiO3(0.001<=Y<=0.5), MgZSr1-ZTiO3(0.001<=Z<=0.5). The second constituent consists of at least one type out of Nb2O5, Ta2O5, WO3, DY2O3, Y2O3, La2O3, CeO2, Sm2O3, Pr6O11, and Nd2O3. It allows the dielectric constant, voltage non- linear index, surge withstand amount, etc., to be increased. |
