Manganese is a chemical element, designated by the symbol Mn.
the atomic number 25. It is found as a free element in nature (often in
combination with iron), and in many minerals.
Manganese is a gray-white metal, resembling iron.
a hard metal and is very brittle, fusible with difficulty, but easily
Manganese metal and its common ions are paramagnetic.
Manganese is a metal with important industrial metal alloy uses.
Manganese ions are variously colored, and are used industrially as
pigments and as oxidation chemicals.
Manganese metal is ferromagnetic only after special treatment. The pure
metal exists in four allotropic forms. The alpha form is stable at
ordinary temperature; gamma manganese, which changes to alpha at
ordinary temperatures, is said to be flexible, soft, easily cut, and
capable of being bent.
Manganese has played a key role in the development of various
steelmaking processes and its continuing importance is indicated by the
fact that about 90% of all manganese consumed annually goes into steel
as an alloying element.
Manganese is a key component of low-cost stainless steel formulations
and certain widely used alumimum alloys.
Manganese dioxide is also used as a catalyst.
Manganese is used to decolorize glass and make violet coloured glass.
Potassium permanganate is a potent oxidizer and used as a disinfectant.
compound that find application are Manganese oxide (MnO) and manganese
carbonate (MnCO3): the first goes into fertilizers and ceramics, the
second is the starting material for making other manganese compounds.
human body, manganese functions as an enzyme activator and as a
component of metalloenzymes.
Manganese activates the enzymes responsible for the utilization of
several key nutrients including biotin, thiamin, ascorbic acid, and
world production of manganese alloys reached 11.8 million metric tons.
a manganese ore production of over 34 million tons per year, 13 million
tons come onto the international market. A few producing countries,
Australia, Brazil, Gabon and South Africa, account for over 85% of the
most of the manganese requirements of industrialized countries are
supplied in the form of alloys. As a result, the UK and Germany have has
almost completely abandoned local production of manganese alloys and the
USA is now only a minor producer. In Europe, countries such as France,
Norway and Spain have continued to be large exporters of these
