    For some materials, adding liquid nitrogen or carbon dioxide can help embrittle the particles and enhance grindability. Grinding any material depends on particle defects, such as cracks, crystals, or radiation, or on mechanically induced defects. Microcracks or defects encourage crack propagation during grinding.The MiniBeadbeater can be used in a 'dry grinding' mode either at ambient or at liquid nitrogen temperatures. For example, a single seed can be pulverized into a fine powder in 30 seconds using three 3.2 mm diameter or one 6.3 mm diameter chrome steel bead in the vial. Hair can be powdered at liq N2 temperatures using similar sized steel beads.
