Acta Metall Sin

Abstract The mixture powders of carbon nanotubes (CNTs) and aluminum were high-energy ball-milled, and then the CNT/Al composites with different CNT contents were fabricated using a power metallurgy method.Microstructure examinations show that a certain volume of CNTs can be uniformly dispersed in the Al matrix by ball-milling and the CNTs have a close bonding with the Al matrix.

Ball milling oxides – Dalton Transactions Blog

The pestle and mortar still has a place in many chemistry labs but nowadays mechanically-induced chemistry is performed with the help of a high-energy ball mill. In their latest Dalton Transactions Perspective, Vladimir Šepelák, Sylvie Bégin-Colin and Gérard Le Caër describe how ball milling is used to effect transformations in oxides.

Making Black Powder with a Ball Mill

We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.
