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 dissolution rate increased when ball milling time was increased from 30 min to 60 min, as shown in Fig. 6. However, at longer periods (>45 min), the mixtures became sticky and had poor flowability and was difficult to extract from the milling jar. Dissolution rate in 60 min ball milling time was similar to that in 45 min.
