    Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. Manganese metal and its common ions are paramagnetic. Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen. Naturally occurring manganese is composed of one stable isotope, Mn. Eighteen radioisotopes have been isolated and described, ranging in atomic weight from 46 u( Mn) to 65 u ( Mn). The mo

  • Manganese Element information, properties and uses

    Manganese is an extremely versatile element. It can exist in six different oxidation states. In nature, it is usually found in either its reduced +2 state, which easily dissolves in water or in the +4 state, which forms many types of insoluble oxides. The +3 form of manganese is used as a powerful weapon, by dry rot fungi that break down wood

    Manganese (Mn) is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. Steelmaking, including its ironmaking component, accounts for most domestic manganese demand, presently in the range of 85% to 90% of the total. Manganese ferroalloys, consisting of various grades of ferromanganese and silicomanganese, are used to
