Niobium

Niobium (Nb)

Niobium is the 41st element in the periodic table and has a symbol of Nb and atomic number of 41. It has an atomic weight of 92.90637 and a mass number of 93. Niobium has forty-one protons and fifty-two neutrons in its nucleus, and forty-one electrons in five shells. It is located in group five, period five and block d of the periodic table. Soft, ductile grey-blue metallic transition element. Used in special steels and in welded joints to increase strength. Combines with halogens and oxidizes in air at 200 degrees celsius. Discovered by Charles Hatchett in 1801 and isolated by Blomstrand in 1864. Called Columbium originally.

History

Niobium was discovered by the English chemist Charles Hatchett in 1801 and named the new element columbium. In 1846, German chemist Henrich Rose independently discovered the element and named it niobium. The metal was first isolated by Swedish scientist Christian Wilhelm Blomstrand in 1864 who reduced the chloride by heating it in a hydrogen atmosphere. Named after Niobe, the daughter of Tantalu

DiscoverersCharles Hatchet
Discovery LocationEngland
Discovery Year1801
Etymology (Name Origin)From Niobe; daughter of the mythical Greek king Tantalus.
Pronunciationni-OH-bee-em (English)
Some niobium compounds are highly toxic
Brazil is the leading producer of niobium

Uses

Niobium is used in arc-welding rods for stabilized grades of stainless steel. Niobium alloys are strong and are often used in pipeline construction. The metal is used in superalloys for jet engines and heat resistant equipment. Niobium is found in many medical devices such as pacemakers. Used as an alloy with iron and nickel. It can be used in nuclear reactors and is known to be superconductive when alloyed with tin, aluminum or zirconium.

Sources

Occurs in a mineral columbite. Formerly known as colombium (Cb). It is used in stainless steel alloys for nuclear reactors, jets and missiles.
