Abstract

In this paper, the relationship between additive particle size and properties of AgSnO2 contact materials was studied. La2O3 and Bi2O3 were selected as additives for contact materials. AgSnO2 contact materials were successfully prepared by powder metallurgy, the wettability and electrical contact properties of AgSnO2 contact materials with five particle sizes of additives were investigated. The results show that the wettability and electrical contact properties of the two contact materials are better when the particle size of additives is 500 nm and 1000 nm respectively. © 2022 Institute of Electrical Engineers of Japan.
