Abstract

The sample was a mixture of tantalum pentoxide and graphite, vacuum pressed into a briquette and reduced at about 3100 degree C. Argon was used as the arc gas. The elimination reaction of oxygen and carbon proceeds rapidly in the molten state. High purity massive tantalum which contains little carbon or oxygen is produced after a short reaction time.
