Mineral Resource of the Month: Tantalum | EARTH Magazine

Tantalum — a rare, blue-gray, very hard transition metal — was discovered in 1801 or 1802. However, extensive use of the metal did not begin until 1940, when it became an important material for capacitors used in electronics. Tantalum is almost always found with niobium.

Tantalum is the third most refractory metal, with a melting point of 2980℃, only after tungsten and rhenium.Besides, tantalum also has other excellent properties like low vapor pressure, good cold workability, high chemical stability, strong resistance to liquid metal corrosion, and large dielectric constant of the surface oxide film.

Tantalum - Wikipedia

Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum makes it a …

Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum. The name Tantalite has been discredited by the IMA , with the more specific designations of Tantalite-(Fe) (also known as Ferrotantalite ), and Tantalite-(Mn) (also known as Manganotantalite ) being used for this mineral's IMA-accepted nomenclature.

Niobium and tantalum - USGS

Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys used in pipelines ...
