High-energy ball milling is a mechanical process used to grind materials into fine powders. It involves placing the material and hard balls in a rotating container, where the balls collide with the material, causing it to break down into smaller particles. This technique is commonly used in the fields of materials science and metallurgy to create alloys and nanomaterials. The process can enhance the properties of materials by increasing their surface area and promoting chemical reactions. High-energy ball milling is often employed in the production of nanocomposites, ceramics, and metallic powders, making it a valuable tool in research and industrial applications.
