US3637370A - Production of ferrovanadium alloys -

A method of producing a low-carbon low-oxygen ferrovanadium alloy by carbon reduction in which an agglomerated mixture of comminuted vanadium oxide, preferably a pentoxide, an iron-source material, and a carbon-source material are heated in vacuum to a temperature of 2,400*-2,800* F. The temperature is maintained until evolution of gas substantially ceases and the product fuses.
