Abstract
Vanadium-carbon materials for use as additions to steel have been produced by the vacuum furnacing of a mixture of vanadium oxide and carbon. To lower the sulfur content of such material, which derives essentially from the sulfur content of the carbon in the mixture, a relatively small quantity of silicon, silica or tin is included in the mixture prior to vacuum furnacing.
