Tantalum alloys with other elements have great strength, good ductility and high melting points. Niobium is mainly noted for its enhancement of strength and toughness in stainless steel (Tantalum-Niobium International Study Center). Table 2.2 - Properties of Tantalum and Niobium Metal. Density.

A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits.It consists of a pellet of porous tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode.Because of its very thin and relatively high permittivity dielectric layer, the tantalum …

Other illegally-traded materials have now become popular, such as cassiterite, wolframite, and coltan (tin, tungsten and niobium/tantalum ores) due to the widespread use of these metals in consumer electronics, medical devices, and military applications.

Niobium minerals in zwitter and lithium–fluorine granite of the Verkhneurmiysky granitic massif in the Amur River region—fergusonite-(Y), euxenite-(Y), samarskite-(Yb), aeschynite, Nb-bearing wolframite— have been described and the similarity of their species composition established. The same-named and crystal-chemically allied minerals …

Properties of tantalum and niobium. The tantalum carbides, niobium carbides, and tantalum niobium carbides from H.C. Starck Tungsten Powders have an especially narrow grain-size distribution and an extremely low level of impurity. H.C. Starck offers binary mixed carbide powders with ratios between (Ta,Nb)C 90/10 and (Ta,Nb)C 50/50.

Tantalite and tantalum. Tantalite is the mineral or ore, and tantalum is the metallic element which can be extracted by chemically processing the ore. Technically, tantalum minerals do not undergo "smelting", although for convenience, this chemical processing is often referred to as smelting in the broader context of 3TG minerals.

Coltan and wolframite are paramagnetic, while cassiterite, muscovite and quartz are non-magnetic. Magnetite is the mineral with the highest magnetic susceptibility and therefore a low magnetic field (< 0.5 T) would allow magnetite to be separated from the remaining non-magnetic part. ... Tin-tantalum-niobium mineralization in the Penouta ...

Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite.. Tantalum from coltan is used to manufacture …
