Ball Milling an overview ScienceDirect Topics
12.2.1.4 Ball milling Ball milling is often used not only for grinding powders but also for oxides or nanocomposite synthesis and/or structure/phase composition optimization [14,41]. Mechanical activation by ball milling is known to increase the material reactivity and uniformity of spatial distribution of elements [63].

Transformations in oxides induced by high-energy ball
The basic understanding of the mechanisms by which oxides or oxide mixtures evolve by high-energy ball- milling appears to be less advanced than it is for metallic materials essentially because of the overall complexity of the oxide structures, of their surfaces, of their defects and of their mechanical behavior.
