The analytical application of the galvanic dissolution of niobium and tantalum : the determination of nitrogen

Creator:

VanSanten, Richard Theodore

Abstract:

Nitrogen is a contaminant of niobium and tantalum adversely affecting the workability of the metal. With recent interest in the refractory metals, one problem the chemical analyst must solve is the accurate determination of nitrogen in niobium and tantalum at very low levels. The usual method of assaying for nitrogen...

The study of fluo-tantalum species by solvent extraction

Creator:

Coker, Marjory Carol

Abstract:

The extraction of tantalum fluoride complexes by large cationic extractants (tetraphenylarsonium ion, TPA, and crystal violet) and by methyl isobutyl ketone (MIBK) has been investigated as a function of fluoride concentration using ¹⁸² Ta as tracer. Extractions by the cationic extractants into chloroform were carried out in the absence of...
