PROCESS FOR PRODUCING ZINC OXIDE VARISTOR HAVING HIGH POTENTIAL GRADIENT AND HIGH NON-LINEARITY COEFFICIENT

摘要

The process for producing a zinc oxide varistor is disclosed , the non- equivalence with ion step to be fully screen the semiconductor doped zinc oxide particles and the solid- phase is another one for producing the sintered powder having a characteristic impedance of runs in each of the two separate processes , the zinc oxide varistor produced by this process are high potential gradient and a high non- linear coefficient , and characterized by having , in particular the disclosed process is 2,000 to 9,000 V / mm of the electric potential gradient of 21.5 to 55 as well as the non- specific zinc oxide varistor produced having a linear coefficient ( ) it is suitable for .
