PURPOSE:To increase dielectric constant, voltage non-linearity index, surge withstand amount, etc., by incorporating a third element W2N 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 W2N 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 SrTiO3, 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 os 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. |
