A ball is bursting through the material and leads to collisions of big, white-green cubes with blue cubes. This scene symbolically illustrates a solid-state reaction in a ball mill between aminosilsesquioxane and cyclic anhydrides, leading to the rapid, waste-free formation of silsesquioxane amic acids.

In this paper, we present a first attempt to define the basic geometry, mechanics, and physics of the process of mechanical alloying. The geometry of the collision events which lead to particle fragmentation and coalescence is modeled on the basis of Hertzian contacts between the grinding media which entrap a certain amount of material volume between the impacting surfaces. This …
