  • Ball Milling an overview ScienceDirect Topics

    Ball milling (solid state synthesis) is one of the most important processes used in industry to synthesize nanomaterials, and is also called mechanical alloying or attrition. This method is based on a top down approach, like self assembly of molecules and reducing the size of the larger particles.
