High Energy Milling / Mechanical Alloying / Reactive Milling

route is described as high energy ball milling (HEM). The definition of Reactive Milling (RM) is suitable if during milling a chemical reaction is wanted and observed. The advantage here can be an ultra-fine dispersion of particles in a matrix (e.g. Ag-SnO2 where the starting powder is AgO2 + Ag3Sn) [5].
