  • Synthesis of Nanomaterials by High Energy Ball Milling

    It is a ball milling process where a powder mixture placed in the ball mill is subjected to high-energy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960. It was found that this method termed mechanical alloying could successfully produce fine uniform
