Refining of tantalum and tantalum scrap with carbon - H.C ...

1999-2-17  Tantalum refining can be defined as a process of impurity removal during metal consolidation by different sintering and melting techniques. Oxygen has been considered as a major interstitial impurity in refractory metals, and the most traditional technique used to reduce its content has been deoxidization of refractory metal oxide within the ...
