Battery Electrolytic Manganese Dioxide Mno2 Cas No 1313-13-9 For
Manganese dioxide is also called manganese dioxide powder,
manganese oxide powder, natural manganese dioxide, and natural
manganese dioxide powder is mainly used in the chemical industry
and light industry. It is used in medicine (potassium
permanganate), national defense, communication, electronic
technology, printing and dyeing, photography, ceramics, matches,
soap making, welding, water purification, agriculture and other
industries as disinfectants, oxidants, catalysts, etc. .
Chemical Property of Manganese Dioxide
Black powder, density 5.026g/cm3, melting point 390 °C, insoluble
in water and nitric acid, release oxygen in hot concentrated H2SO4,
produce chlorine in manganese sulfate HCL, form manganese chloride,
co-melt with caustic and oxidant, release Carbon dioxide, which
forms KMnO4, decomposes into manganese trioxide and oxygen at 535 °
C and is a strong oxidant.
Dry battery depolarizer, synthetic industrial catalyst, oxidant,
glass, enamel, ceramic colorant, decolorizer, deironing agent,

Introduction of Manganese Dioxide
Acidity and alkalinity: Manganese dioxide is a non-amphoteric oxide
(not a salt oxide). It is a very stable black powdery solid at room
temperature and can be used as a depolarizer for dry batteries. The
laboratory often uses its oxidizing property and concentrated HCl
to produce chlorine gas: MnO2 1,4- 4 HCl = MnCl 2 dec Cl 2 dec 2H 2
O manganese dioxide is a strong oxidant in acid medium
Manganese dioxide is a [MnO2] octahedron with oxygen atoms on top
of octahedral corners, manganese atoms in octahedrons, and [MnO2]
octahedrons joined together to form single or double chains. These
chains and other chains are co-topped to form The tunnel structure
of the void, the octahedron or the hexagonal close-packed, or the
square densely stacked.
Manganese dioxide is an amphoteric oxide, and there is a
corresponding salt of a perovskite structure such as BaMnO3 or
SrMnO3 (obtained by a chemical reaction in a molten alkali system),
and manganese tetrachloride is also present.
In the case of a reducing agent, it exhibits oxidative properties.
For example, manganese dioxide is placed in a hydrogen stream and
heated to 1400 K to obtain manganese oxide; manganese dioxide is
heated in an ammonia gas stream to obtain brown-black dimanganese
trioxide; and manganese dioxide is reacted with concentrated
hydrochloric acid to obtain 1 chlorine. Manganese, chlorine and
In the case of strong oxidants, it also appears to be reducing. For
example, manganese dioxide, potassium carbonate and potassium
nitrate or potassium chlorate are mixed and melted to obtain a dark
green melt, and the melt is dissolved in water to obtain a compound
of potassium pentoxide, potassium manganate. It is a strong oxidant
in acid medium.
Strong oxidant, does not burn itself, but does not help with
