Jul 04, 2018 Powder processing is a crucial step for solid-state processing, which normally includes in situ chemical reduction method or ball milling method. The ball milling method enjoys greater popularity in the industry as it is much easier to be controlled. Ball milling methods are usually divided into dry ball milling (DBM) and wet ball milling (WBM).
