  • 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 dispersions of oxide particles (Al

  • High-Energy Ball Milling an overview

    During the high-energy ball milling process, the powder particles are subjected to high energetic impact. Microstructurally, (SHS) reaction consists of three stages: component activation, chemical reaction initiation and a synthesis process in bulk with product formation. Schaffer and McCormick (1992) stated that SHS reactions occur when the temperature created by the colliding balls in a
