Manganese Oxide
The principal industrial compounds of manganese include several oxides. Manganous oxide, or manganese monoxide, MnO, is used as a starting material for the production of manganous salts, as an additive in fertilizers, and as a reagent in textile printing. It occurs in nature as the green mineral manganosite. MNO is extremely useful as a feed for various animals. It is one of the vital micro nutrients required in balanced nutrition.
Manganese oxide finds its application in analytical chemistry, ceramic paints, food additive etc.
We offer MNO of various grades ranging from 30% to 62% Mn content. Our MNO has traces of non-acid soluble manganese content to give maxium purity to material. All grades are prepared under strict hygiene conditions.
