Tantalum & Niobium - AMG Corporate

13-02-2017· Tantalum oxides are used as a material in capacitors used in electronics such as computers, smart phones and video games. Niobium, on the other hand, is used mostly in alloys, such as in specialty steel and titanium.

Tantalum and niobium - Critical Metals Handbook - Wiley

Niobium and tantalum do not occur naturally as free metals. The charge to ionic ratio of tantalum and niobium results in strong bonds being formed with oxygen; in fact, most niobiumtantalum minerals are oxides, rather than silicates, sulfides or phosphates.

A Review of Niobium-Tantalum Separation in

Niobium and tantalum are chemically similar and are associated with each other in nature which makes it very difficult to separate. For many years, the separation of tantalum from niobium involved the fractional crystallization of potassium heptafluorotantalate away from potassium oxypentafluoroniobate monohydrate, this method has been supplanted by solvent extraction from fluoride-containing

US7204866B2 - Niobium or tantalum powder and

A niobium or tantalum powder of the present invention comprises aggregates in which primary particles of niobium or tantalum are aggregated, and have a pore distribution having a peak in the range from 1 to 20 m as measured by mercury porosimetry. That is, the niobium or tantalum powder of the present invention comprises aggregates having large pores, which connect with vacancies between the

Separation and determination of tantalum and niobium

For a tantalum/niobium ratio of 1:1 the niobium coprecipitation is reduced to 5 %. Furthermore, two alternative possibilities are presented: (1) a quantitative recovery of a tantalum precipitate at small oxalate and high tannin concentration, leaving 90% of the tantalum-free niobium in solution; (2) an 85 % recovery of niobium-free tantalum at high oxalate and small tannin concentration.
