Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
The physical exfoliation method usually requires external mechanical forces such as ultrasonication and ballmilling techniques, which have become the mainstream method of BNNS preparation due to its costeffectiveness and ease of production on a large scale [21], [22], [23].

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...
Highenergy ball milling (HEBM) of powders is a complex process involving mixing, morphology changes, generation and evolution of defects of the crystalline lattice, and formation of new phases.

High energy ballmilling method. This technique is very similar to that of mechanical ballmilling technique. Only difference is that this method used very high rpm from few hundreds to few thousands for milling with very small sized balls. This technique uses low temperature for the synthesis of the oxide materials.
