    Particle morphology control of metal powder with various

    Mechanical milling was performed by using a planetary ball mill (PBM) under various experimental conditions. Copper powder (99.0% purity, median particle size x 50 = 45 μm, Aldrich chemistry) was used as shown in Fig. 1.Mechanical alloying (MA) was carried out at two types of rotation speeds: low (10, 50, and 100 rpm) and high (300, 500, and 700 rpm).

    Sep 29, 2014 I once made pyrophoric (!) copper powder using this technique. There are mentions of preparation of iron powder same way. Anyway, it is much more practical than electrolysis for big batches. Frankly speaking, fine aluminium flakes are widely employed in various paints and are dirt cheap. They should be available in shops for artists.

    Nov 01, 2008 If you put it in the ball mill for a few days, all you're likely to get is unusable and pyrophoric aluminum. A bag full of hurt, if you will. Grinding the aluminum seems like just about the hardest and slowest way you could choose to produce it. Milling aluminum without good techniques is a GREAT way to get seriously hurt and make a useless product.
