It is found as a free element in nature (often in combination with iron), and in many minerals. As a free element, manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. %Mn C Si Fe P S Ni Cu Al+Ca+Mg Metal Mn97 97 0.08 0.4 2 0.04 0.04 0.02 0.03 0.7 Metal Mn96 96.5 0.1 0.5 2.3 0.05 0.05 0.02 0.03 0.7 Metal Mn95-A 95 0.15 0.8 2.8 0.06 0.05 0.02 0.03 0.7 Metal Mn95-B 95 0.15 0.8 3 0.06 0.05 0.02 0.03 0.7 Metal Mn93-A 93.5 0.2 1.8 2.8 0.06 0.05 0.02 0.03 0.7 Metal Mn93-B 93.5 0.2 1.8 4 0.06 0.05 0.02 0.03 0.7 Mn % Se % Si % S % C % P % Fe % Electrolytic Metal Mn 99.8 0.06 0.01 0.04 0.02 0.002 0.03
Manganese ions have various colors, depending on their oxidation state, and are used industrially as pigments. The permanganates of sodium, potassium and barium are powerful oxidisers. Manganese dioxide is used as the cathode (electron acceptor) material in standard and alkaline disposable dry cells and batteries.
Manganese(II) ions function ascofactorsfor a number of enzymes in higher organisms, where they are essential in detoxification of superoxide free radicals. The element is a required trace mineral for all known living organisms. In larger amounts, and apparently with far greater activity by inhalation, manganese can cause a poisoning syndrome in mammals, with neurological damage which is sometimes irreversible.
