Synopsis Vanadium is expected to be used as an element in hydrogen storage alloys. One of the main obstacles to this metal being used more commonly in this way is its cost. Pure V refined by electron beam furnace costs more than 60,000 yen/kg in Japan. This paper aims for the realization of a cost efficient process for producing pure V, by refining Al-95V alloy which is almost as cheap as a tenth of pure V. The cold crucible was chosen as a refining furnace because it does not use ceramicdoi:10.4262/denkiseiko.74.13 fatcat:i6enxegrcrb7tjx2xcas6xmhfu
