Dry ball milling and wet ball milling for fabricating copper–yttria
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). DBM is mainly carried out in the environment of gas atmosphere, e.g., argon ambient. WBM is mainly conducted in liquid environment, e.g., ethanol.
