Manganese Dioxide (MnO2) 78-80% CAS 1313-13-9
Manganese Dioxide (MnO2) 78-80% CAS 1313-13-9Manganese Dioxide (MnO2) 78-80% CAS 1313-13-9Manganese Dioxide (MnO2) 78-80% CAS 1313-13-9Manganese dioxide, mainly used as a depolarizer in dry cell batteries, is the most important non-metallic form of manganese. In either traditional alkaline and rechargeable battery cells, Manganese dioxide takes in electrons through a redox reaction, becoming Manganese III oxide. It also has applications in lithium-ion technologies.
It is also the primary precursor to ferromanganese, an alloy of iron used for its lower melting point and low cost.
It is black in appearance and used to color glass and ceramics, as well as for cave art and possibly body paint in prehistorical eras. Further uses include the purification of drinking water, and production of pure oxygen and chlorine.
The chemistry of manganese(III) is not extensive, and in the higher oxidation states manganese dioxide and potassium permanganate are the most important compounds.
Manganese dioxide is also used in the manufacture of glass to bleach the colour of any iron present. If excess manganese dioxide is added, a pink coloration can be produced in the glass and if a large excess is present it will appear black.
Other uses of manganese dioxide include its use as an oxidizing agent in organic chemistry and as an oxidizing agent in safety matches, fireworks and flares. It is also an effective adsorbent for hydrogen sulphide and is also used to colour ceramics.
Manganese(IV) oxide is the most important ore of manganese from which the metal is mostly manufactured. The oxide occurs in nature as the mineral pyrolusite as heavy gray lumps, or black when powdered.
The mineral is used to produce manganese metal, most manganese salts, and also manganese steel and other alloys. The metallurgical applications of manganese(IV) oxide mainly involve making ferromanganese and special manganese alloys. Another important application of manganese(IV) oxide is in manufacturing dry-cell batteries and alkaline cells. The oxide also is a colorant in brick, tile, porcelain and glass; a drier for paints and varnishes; a 552 MANGANESE(IV) OXIDEpreparation for printing and dyeing textiles; a curing agent for polysulfide rubbers; an adsorbent for hydrogen sulfide and sulfur dioxide; an oxidizing agent in many organic syntheses such as quinone and hydroquinone; and a catalyst in laboratory preparation of oxygen from potassium chlorate. Manganese(IV) oxide also is used to make welding rods and fluxes, and ceramic magnets (ferrites); and is an additive to fertilizers.
The mineral is the source of manganese and all its Compounds; largely used in manufacture of manganese steel; oxidizer; in alkaline batteries (dry cells); for making amethyst glass, decolorizing glass; painting on porcelain, faience and majolica. The ppt is used in electrotechnics, pigments, browning gun barrels, drier for paints and varnishes, printing and dyeing textiles.
