1984-2-1  The purification of the same charge by sacrificial deoxidation alone would involve a loss of 7% of the tantalum. The results are explained using available and estimated thermodynamic data for the Ta-C-O system. In view of the present observations, a modification incorporating carbon deoxidation in the refining flow sheet of tantalum is suggested.
