Abstract
A process for milling amorphous solids using a milling apparatus can result in particles having a median particle diameter dof <1.5 μm. The process includes: operating a mill in a milling phase with an operating medium selected from the group consisting of gas, vapor, steam, a gas containing steam and mixtures thereof, and heating a milling chamber in a heat-up phase before the actual operation with the operating medium in such a way that a temperature in the milling chamber, the mill exit or both, is higher than a dew point of the operating medium.
