The content of manganese in the earth's crust is the fifteenth place, which is 0.09%. According to geologists, almost all manganese deposits are almost "same years." This gives scientists the assumption that the aggregation of manganese originated from the universe. Their theory is that about two billion years ago, manganese-rich meteor dust had landed on the surface of the earth, forming a manganese deposit that is now found on land and under the sea.
Pure manganese has a lower melting point and lower strength than iron . It is very easy to rust and cannot be used in practice. This may be the reason why manganese has not been valued for a long time.
Copper alloy containing 12% manganese, its resistance constant, the influence of hot and cold surrounding environment changes, the collector material is few good material.
If 3.5% manganese is added to the steel, the manganese steel is as brittle as glass; if 13% manganese is incorporated into the steel, such manganese steel is both hard and strong, and is an alloy steel with excellent properties. Manganese steel is not magnetized and can be used in areas where ships need to be magnetically shielded.
Potassium permanganate is a compound of manganese that we are familiar with. It can be used as a disinfectant solution for rinsing wounds, to clean the sore throat, and to treat burns.
The incorporation of manganese dioxide in the paint catalyzes the oxidation of the paint surface into air in the film. Therefore, manganese dioxide is generally used as a drier for paints.
Manganese ore mining, crushing, production of various manganese alloys, production of dry batteries, pigments, welding rods, etc. and welding can produce manganese dust or manganese smoke, long-term inhalation can cause manganese poisoning.
