Ball Milling method for synthesis of nanomaterials
1. As the name suggests, the ball milling method consists of balls and a mill chamber. Therefore over all a ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum). 2. The powder of a material is taken inside the steel container.
