FIELD: metallurgy. ^ SUBSTANCE: invention relates to powder metallurgy, in particular, to production of powder materials with particle sizes below 0.2 mcm used in manufacturing cermet and composite materials, as well as those intended for use as fuel for thermite and pyro compositions. An aluminum wire is exploded in a gaseous chemically inert atmosphere. The aluminum powder thus produced is wetted with a solution of boric acid in ethanol with a 0,5 mole/l concentration, the powder being separated from solution in no less than an hour after wetting. ^ EFFECT: increase in thermal stability of aluminum powder to 580 C. ^ 2 tbl, 1 ex |
