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 ...
Nb – Niobium. Niobium, is a chemical element with the symbol Nb and atomic number 41. It is a soft, grey, ductile transition metal, which is often found in the pyrochlore mineral, the main commercial source for niobium, and columbite.
Niobium (Nb), chemical element, refractory metal of Group 5 (Vb) of the periodic table, used in alloys, tools and dies, and superconductive magnets. Niobium is closely associated with tantalum in ores and in properties. Due to the great chemical similarity of niobium and tantalum, the establishment
Jan 20, 2018· Now, when obtaining niobium from ore, it is purified from tantalum and other metals, and so pure niobium pentoxide is acquired, which is then subsequently dissolved with hydrofluoric acid, thereby ...

Tantalum as an investment can be a rather contentious topic among finance experts. Others call it a conflict resource and have linked the use of the metal to the war in the African country once known as Zaire. This war is sometimes called the African World War, and it involved 9 countries and about 20 separate armed groups.
Tantalum and Niobium – the keys to the markets of the future Tantalum is among the rarer elements in the earth's crust. It ranks between thorium and caesium in frequency and is therefore rarer than lanthanum, lead, gallium or boron. Even niobium, which always occurs in association with tantalum, is ten times more available.

Tantalum and Niobium Metal Powders. Tantalum and niobium are refractory metals with melting points of 3,017°C and 2,477°C. They are excellent materials for capacitor anodes as they form an extremely thin but dense oxide layer as dielectric.
Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950. Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in steels and in superalloys.
Word Origin: Greek mythology: Niobe, daughter of Tantalus, as niobium is often associated with tantalum.Formerly known as Columbium, from Columbia, America, the original source of niobium ore. Many metallurgists, metal societies, and commercial producers still use the name Columbium.
Niobium wasn't used in commercial applications until the early 20th century. Today, Brazil is the leader in the production of both ferroniobium, which contains 60 to 70 percent niobium with the rest being iron, and niobium. Price History
