Manganese Oxide is derived from manganese, a brittle metal element. It
is widely distributed in the earth's crust, and is essential in steel-making. The element is needed for plant growth
and in the physical development of higher animals. Manganese is involved in redcing the levels of nitrates in green
plants. Lack of manganese causes testicular atrophy in animals. However, too much in either plants or animals is
toxic.
Historical Background
Manganese was first recognized as an element in 1774 by Carl Wilhelm Scheele while working with the mineral pyrolusite,
and was isolated the same year by his associate, Johan Gottlieb Gahn.
Manganese Tetroxide
Manganese oxide is the most important manganese compound. Pyrolusite is the chief source of manganese and all its
compounds, when derived from ores. Pyrolusite is widely used as a chemical oxidant in organic synthesis. Manganese
oxide is also used as the cathode material in electric dry cells. Synthetic manganese oxide is prepared by decomposition
of manganese nitrate; by reaction of manganese sulfate, oxygen and sodium hydroxide; or by electrolysis of an aqueous
solution of manganese sulfate.
