Effect of Feeding Rate on Properties of Cu-Ag Alloy Nanopowders

Abstract

The relations between specific surface area, morphologies and collection rate, feeding rate of Cu-Ag alloy nanopowders prepared by plasma induction system were studied by specific surface area tester and SEM. The results show that with the increase of powder feeding rate from 300g/h to 500g/h and to 800g/h, the collection rate decreases from 59.1% to 47.2% and to 46.1%, respectively, and the specific surface area accordingly decreases from 9.25m2/g to 7.17m2/g and to 5.45m2/g.
