METHOD OF ALUMINIUM POWDER ACTIVATION Russian patent published in 2014 - IPC C09K8/60 B22F1/00 C01F7/42 

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy, particularly, to activation of disperse aluminium powder combustion and can be used in various branches of industry. Proposed method comprises impregnation of initial powder with activator based on vanadium oxide compound. Gel is used as said activator containing 4.0-8.2 g/l of vanadium obtained by melting of vanadium oxide or vanadium oxide and lithium or sodium carbonate or vanadium oxide and boric acid or mix thereof with subsequent addition of the melt to distilled water at intensive mixing and curing. Initial aluminium powder is impregnated with said gel at gel-to-aluminium powder ratio making 2 ml:1 g. Then produced mass is filtered at vacuum filter and dried at 50-60°C for 0.5-1 h.

EFFECT: higher completeness of combustion.
