摘要：

Powders of the vanadium oxides V2O4, V6O13, and V2O5 were produced by thermal decomposition of aqueous solutions of vanadyl sulfate hydrate in atmospheres of N-2, H-2 mixed with N-2, or air. The composition of the oxide powder was determined by the reactor temperature and gas composition. Residual sulfur concentrations in powders produced by decomposition at 740 degrees C were less than 1 at.%, and these powders consisted of hollow, roughly spherical aggregates of particles less than 1 mu m in diameter.
