Introduction Highenergy ball milling is commonly used for particle size reduction (comminution) down to the nanometer scale [6], [16], [62]. Increased surface energy and defectivity lead to modified physical/chemical properties and can promote structural transformations and/or chemical reactions (see [67]).
