Definition of Manganese dioxide or peroxide

Manganese dioxide or peroxide
Manganese Man`ga*nese", n. [F. mangan[`e]se, It. manganese, sasso magnesio; prob. corrupted from L. magnes, because of its resemblance to the magnet. See Magnet, and cf. Magnesia.] (Chem.) An element obtained by reduction of its oxide, as a hard, grayish white metal, fusible with difficulty, but easily oxidized. Its ores occur abundantly in nature as the minerals pyrolusite, manganite, etc. Symbol Mn. Atomic weight 54.8. Note: An alloy of manganese with iron (called ferromanganese) is used to increase the density and hardness of steel. Black oxide of manganese, Manganese dioxide or peroxide, or Black manganese (Chem.), a heavy black powder MnO2, occurring native as the mineral pyrolusite, and valuable as a strong oxidizer; -- called also familiarly manganese. It colors glass violet, and is used as a decolorizer to remove the green tint of impure glass. Manganese bronze, an alloy made by adding from one to two per cent of manganese to the copper and zinc used in brass.
