Manufacturing of aluminum flake powder from .
Intermediate stops during the ball milling produced a finer aluminum flake powder than nonstop milling for up to 25 h due to cooling of the vial. A larger amount of stearic acid reduces friction between the foil or the balls and vial wall, thus give less milling efficiency, 3 wt.% of stearic acid as additive being verified as the optimum content. The aluminum flake powder produced by the dry ...
