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].
Titania 1. Introduction Ball milling is a mechanical technique used to grind powders into fine particles [1]. Generally, a ball mill consists of a hollow cylindrical vessel that rotates around its axis and balls which are made of materials such as steel, stainless steel, ceramic or rubber.
