Oxidation of Vanadium in Dry and Moist Oxygen–Argon Mixtures

Abstract

VANADIUM is notable for its very rapid rate of oxidation at temperatures above 675° C, at which temperature the main oxidation product, V2O5, melts. The presence of V2O5 in the oxide scale of other metals, either through the presence of vanadium as an alloying constituent, or through its introduction from furnace ash, may also cause rapid attack (so-called catastrophic oxidation), usually above about 650° C. This is usually ascribed to the fluxing action of the molten V2O5 on the oxide of the basis metal1.
