DescriptionECHEMI Editorial ReferenceManganese is a combustible, lustrous, brittle, silvery soft metal. It may be found in chunks, powder, or flakes. The most important ore containing manganese is pyrolusite. Manganese may also be produced from ferrous scrap used in the production of electric and open-hearth steel.

Manganese appears as a lustrous brittle silvery solid. (NIOSH, 2016)|Manganese is a naturally occurring metal that is found in many types of rocks. Pure manganese is silver-colored, but does not occur naturally. It combines with other substances such as oxygen, sulfur, or chlorine. Manganese can also be combined with carbon to make organic manganese compounds. Common organic manganese compounds include pesticides, such as maneb or mancozeb, and methylcyclopentadienyl manganese tricarbonyl (MMT), a fuel additive in some gasolines.Manganese is an essential trace element and is necessary for good health. Manganese can be found in several food items, including grains and cereals, and is found in high amounts in other foods, such as tea.|Manganese atom is a manganese group element atom. It has a role as an Escherichia coli metabolite and a micronutrient.|Manganese is naturally occurring in the environment. Manganese is essential for normal physiologic functioning in humans and animals, and exposure to low levels of manganese in the diet is considered to be nutritionally essential in humans. Chronic (long-term) exposure to high levels of manganese by inhalation in humans may result in central nervous system (CNS) effects. Visual reaction time, hand steadiness, and eye- hand coordination were affected in chronically-exposed workers. A syndrome named manganism may result from chronic exposure to higher levels; manganism is characterized by feelings of weakness and lethargy, tremors, a mask-like face, and psychological disturbances. Respiratory effects have also been noted in workers chronically exposed to manganese bearing particles by inhalation.|A trace element with atomic symbol Mn, atomic number 25, and atomic weight 54.94. It is concentrated in cell mitochondria, mostly in the pituitary gland, liver, pancreas, kidney, and bone, influences the synthesis of mucopolysaccharides, stimulates hepatic synthesis of cholesterol and fatty acids, and is a cofactor in many enzymes, including arginase and alkaline phosphatase in the liver.

Experimental Properties:One stable isotope: 55; exists in 4 allotropic forms: alpha form: body-centered cubic, stable below approx. 710 °C, density (at 20 °C): 7.47; beta form: cubic, stable in the range 710-1079 °C, density (at 20 °C): 7.26; gamma form or electrolytic manganese: face-centered cubic, stable in the range 1079-1143 °C, density (at 1100 °C): 6.37; delta form: body-centered cubic, stable in the range 1143 °C to melting point, density (at 1143 °C): 6.28; gamma manganese when stabilized at room temperature is face-centered tetragonal, density (at 20 °C): 7.21; melting point: 1244 °C; boiling point: 2095 °C|Superficially oxidized on exposure to air. Burns with an intense white light when heated in air. Decomposes in water slowly in the cold, rapidly on heating; pure electrolytic manganese is not attacked by steam. Reacts with dilute mineral acids with evolution of hydrogen and formation of divalent manganous salts. Reacts with aqueous solns of sodium or potassium bicarbonate. When heated in nitrogen above 2000 °C burns to form a nitride. Converted by fluorine into the di- and trifluoride, by chlorine into the dichloride.

Air and Water Reactions:Manganese dust (finely divided) has been known to be pyrophoric. During a fire in an industrial bag filter, a mixture of aluminum and manganese dusts was released and an explosion resulted [Occ. Haz. 28:185-7. 1946-47].
Reactive Group:Metals, Less Reactive
Reactivity Alerts:Pyrophoric
Reactivity Profile:Manganese dust(finely divided) has been known to be pyrophoric. Powdered manganese ignites in chlorine and burns brilliantly; with fluorine the reaction takes place with incandescence [Mellor 12:185, 344. 1946-47]. Concentrated nitric acid reacts with manganese with incandescence and a feeble explosion [Mellor 12:188. 1946-47]. Manganese or potassium ignites in nitrogen dioxide [Ann. Chim. et Phys.(2) 2:317]. Manganese burns with a brilliant flame when heated in sulfur dioxide vapor [Mellor 12:187. 1946-47]. Contact with conc. hydrogen peroxide causes violent decomposition and/or ignition.

NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Separated from acids. Dry.Prior to working with this chemical you should be trained on its proper handling and storage. Manganese must be stored to avoid contact with water and steam since flammable hydrogen gas is produce. Store in tightly closed containers in a cool, well ventilated area away from oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates). Protect storage against physical damage.
