Vanadium, Niobium, and Tantalum Patty's Toxicology

Vanadium, niobium, and tantalum pentaoxides are the main products of air oxidation at high temperatures vanadium can also form trioxide and tetraoxide under these conditions. At elevated temperatures, metals combine with some nonmetals, for example, with hydrogen, nitrogen, carbon, and silica, giving compounds, many of which are interstitial

What are The Uses of Tantalum samaterials

During the production of tool and cutting steels that contain carbides, tantalum and niobium carbide are added to increase performance and stability. Manufacturers of optical lenses use tantalum oxides to improve the refractive index of their products allowing for thinner lens profiles.

TUNGSTEN, MOLYBDENUM, TANTALUM AND NIOBIUM FOR MEDICAL TECHNOLOGY APPLICATIONS Tungsten. Tungsten is remarkable for its robust physical properties. Tungsten combines excellent corrosion resistance with the highest melting point, lowest vapor pressure, and highest tensile strength at temperatures above 1,650°C of all metals.

Tantalum Definition of Tantalum by Lexico

'A second element, tantalum, is always present in these minerals along with niobium.' 'The initial spark was a press release from the TantalumNiobium International Study Centre calling for a boycott of tantalum mined illegally in world heritage sites in the Congo.'

Tantalum and Niobium Technology Roadmap

201693&ensp·&enspNiobium oxide powder has a similar morphology to that of tantalum and niobium metals can be processed in the same way. This paper compares features of capacitors made from tantalum, niobium metal (nitride doped) and niobiumoxidepowders.The basic material features are summarized in Figure 2:


2011112&ensp·&enspNiobium was evaluated as a cheaper alternative to tantalum in capacitors,[61] but tantalum capacitors are still predominant. Niobium is added to glass in order to attain a higher refractive index, a property of use to the optical industry in making thinner corrective glasses.

Tantalum Element information, properties and uses

Tantalum now sits below niobium in the periodic table. It has an atomic number of 73, and an atomic weight of just under 181. It always takes a valence of 5, so, for example, its oxide contains two atoms of tantalum and five of oxygen.

Tantalum an overview ScienceDirect Topics

Tantalum is a relatively rare element, and commercial quantities are found in Australia, Brazil, Canada, and Africa. Tantalum is also present in tinbearing ores and remains in the slag from tin refinement. Tin processing is, in fact, the primary source of commercial tantalum, since the processing of other sources are much more costly.

H.C. Starck Tantalum and Niobium Compounds & Chlorides

Our tantalum and niobium oxalate solutions are completely soluble compounds that can be used for mixtures at atomic level. These mixtures are applied for example in the production of alytic converters and electroceramics. One example of oxalates is our niobium ammonium oxalate.
