Manganese oxide Specification

The Manganese(ii) oxide with CAS registry number of 1344-43-0 is also called Manganous oxide. Its EINECS registry number is 215-695-8. The IUPAC name is oxomanganese. In addition, the molecular formula is MnO and the molecular weight is 70.94. It belongs to the class of Inorganics.

Preparation of Manganese(ii) oxide: it can be prepared by manganese dioxide and hydrogen. The equation as follows: MnO2 + H2 → MnO + H2O. The manganese dioxide can also react with carbon henoxide to give manganese(ii) oxide. The equation as follows: MnO2 + CO → MnO + CO2. It can also be prepared by heating MnCO3 in vacuo: MnCO3 → MnO + CO2.

Uses of Manganese(ii) oxide: Together with manganese sulfate, it is a component of fertilizer and feed additives. It is used for the production of ferrite materials, paints and desiccant varnishes, catalyst for amyl alcohol production, feed auxiliary agent and trace element such as fertilizer. Also it can be used in medicine, metallurgy, welding, printing and dyeing fabric, glass coloring, oil bleaching, porcelain ceramic, and the manufacture of dry batteries and so on.

When you are using this chemical, please be cautious about it as the following:
It is harmful in contact with skin and irritating to eyes, respiratory system and skin. When you are using it, wear suitable protective clothing. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
