The female magnes ore did not attract iron, but was used to decolorize glass.This feminine magnes was later called magnesia, known now in modern times as pyrolusite or manganese dioxide.Ionized manganese is used industrially as pigments of various colors, which depend on the oxidation state of the ions.The permanganates of alkali and alkaline earth metals are powerful oxidizers.The primary decay mode before the most abundant stable isotope, Manganese isotopic contents are typically combined with chromium isotopic contents and have found application in isotope geology and radiometric dating.
Mn–Cr isotopic ratios reinforce the evidence from ).
Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, which he did by reducing the dioxide with carbon.
Manganese phosphating is used for rust and corrosion prevention on steel.
Manganese is a chemical element with symbol Mn and atomic number 25.
It is not found as a free element in nature; it is often found in minerals in combination with iron.
Manganate (VI) salts can be produced by dissolving Mn compounds, such as manganese dioxide, in molten alkali while exposed to air.
