ball milling process of copper denmark

During the ball milling process the collision between the tiny rigid balls in a concealed container will generate localized high pressure Usually ceramic flint pebbles and stainless steel are used 25 In order to further improve the quality of dispersion and introduce functional groups onto the nanotube surface selected chemicals can be included in the container during the process
