Nanoceramics from the ball mill Max Planck Society

2019-10-30  His team investigated whether a catalytic reaction in such a mill works better because the catalyst is always given a fresh surface where the reactants can meet. They used a soft alumina (gamma-alumina) mixed with gold particles as a catalyst and followed the process in the ball mill with various analytical methods.
