摘要:
Method of forming metal powders from the liquid metal reduction of metal oxides are described. The methods described include the steps of low temperature liquid metal reduction of the oxide, agitation of the reduction reaction mixture and/or distillation of excess reductant upon completion of the reduction step. These steps are designed to limit agglomeration and enhance the purity of the final powder produced. Metal powder produced in accordance with this invention has a basic particle size of 0.1 to 0.5 microns.
