Manganese is a chemical element; it has symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.
Manganese (II) sulfate usually refers to the inorganic compound with the formula MnSO 4 ·H 2 O. This pale pink deliquescent solid is a commercially significant manganese (II) salt. Approximately 260,000 tonnes of manganese (II) sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds.
Electrolytic manganese dioxide. [edit] Electrolytic manganese dioxide (EMD) is used in zinc–carbon batteries together with zinc chloride and ammonium chloride. EMD is commonly used in zinc manganese dioxide rechargeable alkaline (Zn RAM) cells also. For these applications, purity is extremely important.
Infobox references. Manganese (II) oxide is an inorganic compound with chemical formula MnO. [ 2 ] It forms green crystals. The compound is produced on a large scale as a component of fertilizers and food additives.
Manganese oxide is any of a variety of manganese oxides and hydroxides. [1] These include. Manganese (II) oxide, MnO. Manganese (II,III) oxide, Mn 3 O 4. Manganese (III) oxide, Mn 2 O 3. Manganese dioxide, MnO 2. Manganese (VI) oxide, MnO 3. Manganese (VII) oxide, Mn 2 O 7.
Manganese (II) chloride is the di chloride salt of manganese, MnCl 2. This inorganic chemical exists in the anhydrous form, as well as the di hydrate (MnCl 2 ·2H 2 O) and tetrahydrate (MnCl 2 ·4H 2 O), with the tetrahydrate being the most common form. Like many Mn (II) species, these salts are pink, with the paleness of the color being ...
Manganese (II) acetate are chemical compounds with the formula Mn (CH3CO2)2· (H2O)n where n = 0, 2, 4. These materials are white or pale pink solids. Some of these compounds are used as a catalyst and as fertilizer. [3]
Ferromanganese. Ferromanganese metal, note mirror-like sheen responsible for German name spiegel. Ferromanganese is an alloy of iron and manganese, with other elements such as silicon, carbon, sulfur, nitrogen and phosphorus. [ 1 ] The primary use of ferromanganese is as a type of processed manganese source to add to different types of steel ...
