PURPOSE:To obtain the title composition proper for absorbing a surge by specifying the component, composition ratio and loadings of a bismuth borosilicate glass frit added to zinc oxide. CONSTITUTION:A 0.2-1.0wt.% bismuth borosilicate glass frit containing Bi of 0.05-2.0mol% in terms of Bi2O3, Sb of 0.05-2.0mol% in terms of Sb2O3, Co of 0.1-2.0mol% in terms of CoO, Mn of 0.1-3.0mol% in terms of MnO, Ni of 0.05-2.0mol% in terms of NiO, Ti of 0.05-2.0mol% in terms of TiO2, Si of 0.05-3.0mol% in terms of SiO2, Al of 0.001-0.5mol% in terms of Al2O3, and 1-10wt.% CoO is added to zinc oxide. Accordingly, a voltage nonlinear resistance composition having excellent high-temperature load lifetime characteristics and pulse lifetime characteristics can be acquired. |
