1 Answer. Sorted by: 2. It rapidly oxidized. If the ball mill is sealed for long periods of time the oxygen inside the ball mill is consumed coverting aluminum to aluminum oxide. When the lid is opened the aluminum is rapidly oxidized with a exothermic reaction. If the temperature gets hot enough it can spontaneously ignite.

Aluminum is made into a very thin sheet. It is then glued to a piece of paper. The paper is shreaded down to a fine powder (probably around 200 mesh or so). Then it is put into a kiln and the paper is burned off. This is what gives it it's dark color. The powder is then hammer milled to make even finer.
