High-energy ball milling of nonstoichiometric compounds

The milling energy E mill depends on the design specs of the mill and movement of the milling bodies in the milling chamber; it is also a function of milling time t. The theore–tical time dependence of the milling energy E mill was elucidated in Ref. [ 36 ] by an example of using a PM-200 Retsch planetary ball mill.

Ball Milling - an overview | ScienceDirect Topics

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
