1 Summary of electrolytic manganese industry
1.1 Definition and properties
Mn is the symbol of manganese, which is a chemical element in the VIIB group of the periodic table with an atomic number of 25. Its density is 7 . 43 g?cm?3 . The melting point and boiling point of manganese are 1519 K (1246°C or 2275°F) and 2334 K (2061°C or 3742°F) respectively . Manganese is a silvery-gray metal that resembles iron . It is hard and very brittle, difficult to fuse, but easy to oxidize . Manganese is reactive when pure, and as a powder it will burn in oxygen . It reacts with water (rusting like iron) and dissolves in dilute acids . It is an important trace element which is essential for all species and is widely distributed in soil and oceans . As the 12th most abundant element in the Earth’s crust, it is widely used in alloys, batteries and chemicals.
