Role of Ball Milling of Aluminum Powders in Promotion of …
Effect of ball milling (BM) of an aluminum powder on hydrogen generation through a reaction with hot water was investigated. BM increased surface area of t ... milled the powders in an argon (Ar) atmosphere. Ball to powder ratio was 30:1, and the mill speed was maintained at 200 RPM for durations of 0.25, 0.5, 1, 2, 4, 7, 11, and 19 hours ...
