ZNO VARISTOR POWDER
A ZnO varistor powder can be obtained with high operating voltage and excellent current-voltage nonlinear resistance characteristics. In the ZnO varistor powder, the main ingredient is zinc oxide (ZnO); and at least bismuth (Bi), cobalt (Co), manganese (Mn), antimony (Sb), nickel (Ni), and aluminum (Al), calculated as Bi 2 O 3 , Co 2 O 3 , MnO, Sb 2 O 3 , NiO, and Al 3+ , are contained as accessory ingredients in amounts of 0.3 to 1.5 mol% Bi 2 O 3 , 0.3 to 2.0 mol% Co 2 O 3 , 0.3 to 3 mol% MnO, 0.5 to 4 mol% Sb 2 O 3 , 0.5 to 4 mol% NiO, and 0.0005 to 0.02 mol% Al 3+ . ZnO content is greater than or equal to 90 mol%; the bulk density is greater than or equal to 2.5 g/cc; the powder is a spherical powder in which the 50% particle diameter in the particle size distribution is 20 µm to 120 µm.
