Hydrolysis of aluminum dross material to achieve zero
#0183;#32;Al dross powder before use in experiments was ball milling and brought to about 45 m size, using a Fritsch planetary ball mill with stainless steels balls and vials. Balltopowder mass ratio corresponds to 30:1, milling time was set in range 1575 min and was sufficient to obtain Al dross particles size of about 45 m and to get activated aluminum surface.
