Ball Mills are suitable for solvent-free reactions,

nano-sized α-Al 2 O 3 powders were successfully synthesized at low temperatures via unidirectional ball milling of Al(OH) 3 and addition of an AlF 3 additive. The effects of the rotational direction in planetary ball milling on the α-phase transformation and morphology of α-Al 2 O 3 were studied. Unidirectional rotation was observed to be significantly more helpful than ...The Planetary ball mills are the most popular mills used in MM,
