Abstract
A method of uniformly dispersing a nano powder throughout a micron powder. Ordinary mixing or agitation does not succeed in attaining uniform dispersal: the nano powder agglomerates into microscopic masses. In one form of the invention, a charge of a micron powder, with fifty weight percent of charge of nanopowder is loaded into a ball mill. The mixture is ball milled for less than two hours, at room temperature in a dry condition, and produces a highly uniform distribution of the nano powder throughout the micron powder.
