| High-energy ball milling (HEBM) is a mechanical process commonly used to reduce particle size in a wide range of materials.In HEBM, a material is placed into a milling vial that contains a number of small milling balls. The vial is then placed in the high-energy ball mill, where it is shaken vigorously for periods of time ranging from minutes to hours. The milling balls collide with each other and the vial walls, trapping the target material within these collisions. The ongoing impacts and collisions of the milling balls during HEBM impart mechanical energy to the system which causes the material to fracture, thus reducing particle size and creating fresh material surface. |
