Temperature and friction sensitive substances are hard to mill as they are likely to become sticky during processing Cryogenic milling uses liquid nitrogen to freeze substances to 140176C so they become brittle and fit for milling Liquid nitrogen freezing is the most environmentally friendly one among cryogenic freezing methods.
