Controllable Hydrolysis Performance of MgLi Alloys and ...

The ball-milling method is commonly used to refine the particle size and thus may improve hydrolysis kinetics. However, Mg and Li will be easily agglomerated, which means that direct ball-milling could not refine MgLi. In this work, we introduced 10 wt.% expanded graphite into the ball-milling process to synthesize refined MgLi alloy samples.

Realizing facile regeneration of spent NaBH4 with Mg–Al alloy

The alloy was used to react with hydrated NaBO 2 via ball milling under an argon atmosphere in order to regenerate NaBH 4. During the ball milling process, oxide layers on the alloy will be destroyed and fresh surfaces will be produced continuously. This will increase the overall kinetics of the regeneration process.
