Unlike the dry ball-milling process, the present wet milling resulted in the formation of an intermediate titanium nitride Ti 2 N which has never been found in previous studies using dry milling. With increasing milling time, Ti 2 N was observed to gradually transform into the stoichiometric compound TiN.
The use of a liquid phase makes wet milling a more intensive process than dry milling and allows for extremely small particles, even at the submicron level, while in the case of dry milling, particle size cannot be reduced beyond the micron level. As an example, Kotake et al. [44] milled quartz using dry and wet ball milling. They found the ...
