Ball-milling: the behavior of graphite as a function of ...

2002-1-1 · The ball milling of graphite in the presence of a liquid leads to very thin, well-crystallized and anisometric particles. In the presence of water, the graphite particles are covered by γ Fe 2 O 3 (maghemite) formed by the oxidation of the ferrous alloy coming from the milling tools. This composite presents interesting electrochemical properties.

Ball Milling - an overview | ScienceDirect Topics

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
