Manganese(II) sulfide Manganese(II) sulfide Manganese(II) sulfide is a chemical compound of manganese and sulfur. It occurs in nature as the mineral alabandite (isometric), rambergite (hexagonal), and recently found browneite (isometric, with sphalerite-type structure, extremely rare, known only from a meteorite). Manganese(II) sulfide can be prepared by reacting a manganese(II) salt (such as manganese(II) chloride) with ammonium sulfide: The crystal structure of manganese(II) sulfide is similar to that of sodium chloride. The pink color of MnS likely results from poor coupling between the lowest energy unoccupied Mn orbitals, resulting in discrete states rather than a delocalized band. Thus the lowest energy band-to-band electronic
Manganese(II) phosphate due to their toughness. Manganese phosphate coating can often be found in the oil and gas industry, firearms and ordnance, aerospace, gears and bearings, and in marine equipment. They are also common in engines, screws, nuts and bolts, and washers. Manganese(II) phosphate Manganese(II) phosphate is an inorganic compound with the chemical formula Mn(PO). It is a rarely studied species, in contrast to the related lithium manganese phosphate, which has been investigated as a battery cathode. Manganese phosphates often combine with iron phosphates through paragenesis. In the process of paragenesis, each mineral affects the manner in which the other is crystallized.
