Effect of sodium and potassium polyvanadates on aluminum-powder oxidation

The effect of polyvanadates and vanadium oxide bronzes of alkali metals on aluminum-powder oxidation has been studied by thermogravimetry and x-ray phase analysis. The macromechanism of promotion of aluminum oxidation in which the catalytically active component is meltedNa2AlxV12O31 has been established. It is shown that the intermediate product of vanadium-containing slag processing can be used as an activator.
