Ball milling is a key step in the processing of tungsten carbide parts. It ensures a good distribution of the different powders and reduces the crystallite size in the nanometer range by "mechanical alloying". The study of the influence of the rotation speed and the milling medium on the sinterability of the WCCo composite is important.

The wet ball milling (WBM) method is, for the first time, used for the exfoliation of bulk black phosphorus (BP) to obtain fewlayer black phosphorus (FBP). Before that, the rational solidliquid ratio of raw material is determined to be 1:1 (mg/mL) for the popular ultrasound liquid exfoliation (ULE). Obviously, the high proportion of organic solvent used in ULE will lead to serious ...
