Manganese, one of the important members of the ferrous metal family. But before the 1770s. In 1770, Bergmann, a professor of chemistry at Uppsala University in Sweden, separated the soft manganese mine from the lime and white magnesium mines and described it as the mineral ash of a new metal. Later, after three years of research, his friend Carl William Scheller determined that peromanite was an oxide of a new metal, which he named manganese (Manganese). In 1774, Bergman's assistant, John Gotliegn, heated purified soft manganese powder and charcoal in a crucible for an hour, and finally separated pure manganese, obtaining the manganese we know today. Manganese is everywhere in both nature and in daily life, but because it often changes its body shape, so it is easily overlooked.
Manganese, the element symbol is Mn, the atomic number in the periodic table is 25, belongs to the transition metal. Pure metal manganese is silver white, hard and brittle. Because of its lively metal properties, the manganese exposed to the air is often oxidized to form a brown oxide overburden layer. Under heating conditions, manganese is often oxidized to form a layered oxidation rust skin, and the outermost layer is brown and black manganese tetroxide. Clearly has bright metal color manganese, but hidden edge, willing to become a member of the black metal family, it can be said to be deep if virtual.
Application fields of electrolytic manganese metal:
Manganese and manganese alloy is one of the indispensable important raw materials in iron and steel industry, aluminum alloy industry, magnetic material industry and chemical industry. Manganese is an indispensable additive in smelting industry, and electrolytic manganese processing into powder is the main raw material for the production of manganese trioxide. The magnetic materials widely used in the electronic industry are produced with manganese trioxide, and the electronic industry, metallurgical industry and aerospace industry all need electrolytic manganese metal. With the continuous development of science and technology and the continuous improvement of productivity level, electrolytic manganese due of its high purity and low impurities, has been successfully and widely used in iron and steel smelting, nonferrous metallurgy, electronic technology, chemical industry, environmental protection, food hygiene, electrode industry, aerospace industry and other fields.
