Choosing the right strategy: cryogrinding vs. ball milling
网页2021年8月27日 Samples were chilled in liquid nitrogen prior to processing, and cryogenic temperature was maintained during grinding. The mill was operated with the setting of cryogrinding time and speed. The cryogrinding time was counted by cycles (3, 6, 12 and 24) where one cycle included 15 min of precool time, 4 min grinding, and 1 min of rest.
