  • Role of Mixing and Milling in Mechanochemical Synthesis

    Role Of Mixing And Milling In Mechanochemical Synthesis

    the increasing ball weight leads to an increase in the magnitude of the shock energy and promotes the milling and activation of the material, while an increase in the ball size or in the number of balls loaded increases the likelihood of contact of a ball with the material and the reactants with each other on the surface of the ball at the moment of impact [4, 155–160, 170–174].
