ferroniobium

The ferroniobium contains between 60 and 70% of niobium.

The ferroniobium can be purified by electron beam melting or used as it is.

For alloying with steel the ferroniobium is added to molten steel before casting.

Steel producers add the ferroniobium to molten steel before casting to give it its desirable physical characteristics.

The result is aluminium oxide and ferroniobium, an alloy of iron and niobium used in the steel production.

The largest producers of ferroniobium are the same as for niobium and are located in Brazil and Canada.

Brazil is the leading producer of niobium and ferroniobium, an alloy of niobium and iron.

Niobec sells its niobium in the form of ferroniobium, an important iron niobium alloy with a niobium content of 65-70%.

Niobium is mined from pyrochlore deposits, upgraded into a niobium pentoxide (Nb2O5) concentrate and then converted into ferroniobium.

• Production of ferroniobium begins at new plant, Niobec mine, Saint-Honoré, Quebec, about 15 km northwest of Chicoutimi.

The aluminothermic reaction is used for the production of several ferroalloys, for example ferroniobium from niobium pentoxide and ferrovanadium from iron, vanadium(V) oxide, and aluminium.

Iamgold also said that demand for ferroniobium, a strengthening element used in steel manufacturing which it produces from its niobium mine, is seen strong for at least the next two years.

The most common commercial niobium alloys are ferroniobium and nickel-niobium, produced by thermite reduction of appropriate mixtures of the oxides; these are not usable as engineering materials, but are used as convenient sources of niobium for specialist steels and nickel-based superalloys.

As a result of those new rules, waivers were revoked for $266 million worth of gold necklaces and related products from India, $233 million of jewelry from Turkey, $151 million of the alloy ferroniobium from Brazil and $6.6 million of peanuts from Argentina, USTR said.

Appreciable amounts of the element, either in its pure form or in the form of high-purity ferroniobium and nickel niobium, are used in nickel-, cobalt-, and iron-base superalloys for such applications as jet engine components, gas turbines, rocket subassemblies, and heat resisting and combustion equipment.

Community Capacity Building Due to the substantial investment related to underground development and the construction of a converter for the production of ferroniobium, the Niobec mine was recognized with a certificate of gratitude in 1997 for being a major contributor to employment and the economy of the Saguenay region of Quebec.
