Abstract
A process for controlling the oxygen content in tantalum material comprising heating the material under a hydrogen-containing atmosphere in the presence of a tantalum getter metal having an initial oxygen content lower than the tantalum material.
Claims8
A process for controlling the oxygen content in tantalum material comprising heating said material at a temperature ranging from about 900.degree. C. to about 2400.degree. C. under a hydrogen-containing atmosphere in the presence of a tantalum getter metal having an oxygen concentration prior to said heating lower than that of said tantalum material.
