Niobium and tantalum separation by gas-phase fluorination

Pienaar, A.D.; Wagener, J.B.; Crouse, Philippus L. (Elsevier, 2012-11)

The separation of tantalum and niobium compounds has been of interest for many years, with few new developments. Classically separation is achieved by liquid–liquid extraction and most research focuses on optimising this ...
A thermogravimetric study of the reactions of molybdenum disilicide with anhydrous hydrogen fluoride and fluorine

Gama, Jabulani Selby; Wagener, J.B.; Crouse, Philippus L. (Elsevier, 2013-01)

The results of a thermogravimetric study into the dry fluorination of molybdenum disilicide, MoSi2, using hydrogen fluoride and dilute fluorine gas as fluorinating agents are reported. The reaction between molybdenum ...
