Manganese is used extensively to produce a variety of important alloys and to desulfurize and deoxidize steel. Rational for synthesis of novel OMS and OL materials is related to the superb . And there is the "valence" or "combining power" of an element. It has an important role in the synthesis of nutrients like cholesterol, carbohydrates and proteins. The principal industrial compounds of manganese include several oxides. NSF approved. Manganese Oxide. EMD EMD (Electrochemical Manganese Dioxide) is made from electrolysis. It is commonly found with iron as mineral oxide coatings on the surface of soil and rock grains. This coating is insoluble, meaning that it can't be dissolved by another material, thus increasing the part's strength and wear-resistance. Answer (1 of 2): In dry cells, manganese dioxide acts as a 'depolariser'. Magnesium oxide is also used as an antacid to treat indigestion, or as a laxative to relieve occasional constipation. It may refer more specifically to the following . Manganese sulfate is used to make a fungicide. These salts are oxidised by dissolved oxygen to an insoluble ferric and manganic acid.

It is also present in manganese nodules. It's found in foods such as nuts, whole grains, and leafy green vegetables. The manganese dioxide cathode had a little carbon mixed into it as well, which improved conductivity and absorption. A battery with a manganese-rich cathode is less expensive and also safer than one with high nickel concentrations, but as is common in battery research, an improvement in one or two aspects involves a trade-off. In this case, increasing the manganese and lithium content decreases the cathode's stability, changing its performance over time. Manganese is not very reactive in regards to air.
