Manganese (Mn)

Manganese (Mn)

Isolated in 1774, manganese is gray-white, harder than iron, and very brittle. It is reactive chemically and used to form important ferromagnetic and other alloys. Manganese improves the handling of steel, adding strength, stiffness, wear resistance, and hardness.

Pure manganese exists in four allotropic forms. Manganese minerals, including oxides, silicates, and carbonates are common. Manganese is currently obtained from ores and minerals that include pyrolusite and rhodochrosite.

Manganese is an important trace element in biology and may be related to the ability to utilize vitamin B1. The permanganate form is used as an oxidizing agent, in quantitative analysis, and in medicine.
