In particular, for metal powder, ball milling is performed under oxygen-free conditions to prevent oxidation of the sample and thus to prevent the ball milling efficiency and the quality of the sample from being affected.
The prior anaerobic ball milling method is mainly carried out in a vacuum ball milling tank.
The vacuum ball milling jar is generally mostly the metal material, because the metal material is favorable to making sealed system, can seal through sealed lid.
