Manganous oxide

Manganous Oxide is an inorganic compound with the chemical formula MnO. It is a green or pink crystalline solid that is used in various applications, including as a pigment, in ceramics, and in the production of other manganese compounds.

Chemical Properties

Manganous Oxide is a basic oxide and reacts with acids to form manganese salts. It is insoluble in water but dissolves in acids to form manganese(II) salts. When heated, it decomposes to form manganese(III) oxide and oxygen.

Physical Properties

Manganous Oxide is a green or pink crystalline solid. It has a melting point of 1,962°C and a boiling point of 3,000°C. It is insoluble in water but soluble in acids.

Production

Manganous Oxide is produced by the reduction of manganese dioxide (MnO2) with carbon, hydrogen, carbon monoxide, or hydrocarbons at high temperatures. It can also be produced by the thermal decomposition of manganese nitrate.

Applications

Manganous Oxide is used in a variety of applications. It is used as a pigment in ceramics and glass, in the production of other manganese compounds, and as a catalyst in the petrochemical industry. It is also used in dry cell batteries and in the manufacture of ferrites.

Health Effects

Exposure to Manganous Oxide can cause irritation to the eyes, skin, and respiratory tract. It can also cause metal fume fever, a flu-like illness with symptoms such as fever, chills, nausea, and shortness of breath.
