NONLINEAR RESISTOR AND PROCESS FOR PRODUCING THE SAME |
摘要 |
A nonlinear resistor comprising a sintered body containing zinc oxide as a major component and at least bismuth oxide and boron oxide and electrodes formed thereon, said sintered body having a higher gamma -form bismuth oxide phase concentration in upper and/or lower surface layers of the sintered body than in the inner portion of the sintered body, has stabilized properties against long-time voltage application. When the sintered body is further modified by making the gamma -form bismuth oxide phase concentration in the periphery portions of the upper and/or lower surface layers lower than that in the inner portions of the upper and/or lower surface layers, the resulting nonlinear resistor shows a higher long-duration current impulse withstand capability. |
