| titleOfInvention | Process for manufacturing a voltage non-linear resistor and a zinc oxide material to be used therefor |
| abstract | PROCESS FOR MANUFACTURING A VOLTAGE NON-LINEAR RESISTOR AND A ZINC OXIDE MATERIAL TO BE USED THEREFOR Abstract of the Disclosure A voltage non-linear resistor element mainly comprising ZnO, substantially free from internal defects, exhibiting an excellent current impulse withstand capability, can be manufactured by a process wherein an SiC inclusion in the starting ZnO powder is restricted to at most 10 ppm, preferably at most 0.1 ppm, by weight, whereby formation of closed pores in the element is prevented, which is otherwise caused by decomposition of considerable amount of SiC during firing. The starting ZnO powder has an average particle diameter (R) of 0.1-2.0 µm, preferably 0.3-0.8 µm, a particle size distribution within the range of between 0.5R and 2R, of at least 70%, preferably 80%, by weight, needle-like crystals of at most 20%, preferably at most 10%, by weight, and an SiC content as an impurity of at most 10 ppm, preferably at most 0.1 ppm, by weight. |
