process of making copper powder

Preparation of copper powder by glycerol process ...

2002-3-1  The process produces high purity copper powder having a total level of impurity content less than 1 wt.%. The glycerol process using copper acetate as starting salt yields powder with 99.7% purity. The powder produced by this process contains a thin organic surface layer, which helps to prevent the agglomeration and surface oxidation.
