The ball-milling is generally used as a mechanical co-grinding of powders, initially different in nature, up to the preparation of a new powder, homogeneous in composition. The milling is done in cylindrical containers called vials and containing balls. The nature of the milling tools can be as diverse as steel, agate, tungsten carbide…

Ball milling is an important way to achieve powder refine-ment. In the process of ball milling, powders are collided and squeezed by the pellets, causing severe plastic deformation, cold welding, and fracture [25–26]. Many researches reveal that the milling time has a great influence on the particle size and morphology of the powder [25,27–29].
