Tantalum Wikipedia

Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum

Refining of tantalum by sacrificial and carbon deoxidation

Feb 01, 1984 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.
