Combustion of Vanadium-Carbon powder mixtures at low O2 pressure

Description

The combustion of vanadium-carbon powder mixtures at low O2 pressure was studied. The reaction was ignited toy induction heating; a wave-front was observed propagating throughout the reactants. The combustion temperature, Tc, was higher than the melting point of V and metal particles melted and coalesced during combustion. The analysis of the as-obtained products shows the formation of two isostructural compounds delta-VO1-x and delta-VC1-x , characterized by an fcc structure. The reaction that lead to the formation of the carbide was sustained by the reaction between V and O
