About Manganese Dioxide MnO2:

Manganese dioxide

Is an organic compound having the chemical formula


This is also known as Pyrolusite, and it can be found in nature in form of this mineral. Physical characteristics: Black orthorhombic or amorphous crystals. Solubility: It’s not easily soluble with water, weak acid or weak base.

MnO2 has been identified

A polymorph of alpha atoms that allows for the incorporation of various elements (and water molecules), in “tunnels” and “channels” within the manganese dioxide octahedrons. As a cathode for lithium ion batteries, people are interested in the possibility of a-MnO2.

Manganese 2 oxide

An amphoteric dioxide. It’s a stable, black powdery substance at room temperatures and can be used for depolarizing dry batteries. It’s often used in laboratory settings to create chlorine through its oxidizing ability and the action concentrated HCl.

Manganese dioxide is

This is an acidic media oxidant that can be strong. Manganese dioxide is an [MnO2]-octahedron. The top of the Octahedron has the oxygen atom, while the bottom is home to the manganese. To form single or double chains, [MnO2] octahedrons may be linked together. This combination of chains with other chains creates The tunnel structure, which can be either hexagonal, square, or double-packed.

Manganese dioxide is

It is an amphotericoxide, with a corresponding sodium in the form a perovskite structural such as BaMnO3/SrMnO3 (obtained via a compound react in a mole alkali system), and also manganese trichloride.

It is called an oxidizing agent when manganese oxide comes into contact with a reducer. In order to produce manganese oxide (for example), manganese is heated to 1400K in a stream with hydrogen; to create manganese trioxide (for brown-black manganese), manganese is then heated to 1400K in a stream with ammonia; and the manganese is react to concentrated hydrochloric acid for water, chlorine and manganese.

Reductibility is also demonstrated when manganese dioxide comes into contact with strong organic compounds. When manganese oxide, potassium carbonate, potassium citrate, or potassium salt are combined and melted, you can get a dark brown melt. This melt can then be dissolved and cooled to produce potassium manganate.

Manganese dioxide is an acidic media strong oxidant. It acts as a catalyst for the breakdown of potassium chlorate [KClO3] or the breakdown of hydrogen peroxide (“hydrogen peroxide,” H2O2).

Because of its strong oxidant manganese dioxide doesn’t burn on its own, however, it is capable of supporting combustion. It should therefore not be mixed with any flammable material.

Manganese Dioxide MnO2 (CAS 1313-13-9) Product Performance

Black powder or black rhombic crystals are the physical properties. The solubility of the compound is not easy to dissolve in water or weak acids, weak bases, or cold sulfuric acid. It can also be dissolved in concentrated hydrochloric under heating to make chlorine gas.

Manganese dioxide, an amphoteric ore, has chemical properties. The salt is also available as a perovskite, or BaMnO3 structure. This compound reaction occurs in molten alkali systems. You can also find manganese Tetrachloride.

The oxidizing properties of manganese dioxide are revealed when the reducing agents is mixed with it. You can heat manganese dioxide in 1400K hydrogen. To make manganese oxide you need to heat it in another stream. Manganese is then heated in ammonia until it turns brown.

If it is exposed to strong oxidants it will also show a reduction property. In an acid medium, it is a strong antioxidant.

Manganese Dioxide MnO2


The naturally occurring manganese dioxide contains impurities as well as a significant amount of manganese trioxide. Very few deposits have gamma modifications of enough purity that they can meet the demands of the batteries industry.

Manganese dioxide of high purity is needed for production of ferrites, batteries and other uses. Both the battery and ferrite require “chemical manganese oxide”.

1. Chemical Manganese Dioxide

Another method is to use natural manganese dioxide and to then mix dinitrogen trioxidide with water to make a solution of manganese II nitrate. Crystallized Nitrates can be formed by the evaporation water. A temperature of 400°C causes the salt to break down, leaving behind N2O4 as well as a residue of pure manganese oxide. This is how these two processes can be summarized.

MnO2 +N2O4=Mn(NO3)2

2. Manganese dioxide is reduced by carbothermal methods

Another method is to reduce manganese dioxide by carbothermal reduction into manganese (II), oxide, and then dissolve it in sulfuric acid. MnCO was precipitated from the filtrated solution by ammonium carbonate.

For a mix of manganese and iron oxides, the carbonate is heated in air. To finish the process, sodium chlorate was used to dissolve the carbonate in sulfuric acid. In situ, the chloric acid is capable of converting any Mn(III) or Mn(IIO) oxides into carbon dioxide and releasing chlorine byproducts.

3. Manganese epoxide and manganese monoxide

Third is manganese oxide and manganese molybdenum. Mix the two ingredients in a 1:3 ratio to make manganese dioxide.

Mn2O7 + 3 MnO-5 MnO2

Finally, the potassium permanganate’s effect on the manganese Sulfate Crystals gives rise to the desired oxide.

2 KMnO4 + 3 MnSO4 + 2 H2O-5 MnO2 + K2SO4 + 2 H2SO4

4. Electrolytic Manganese Dioxide

EMD is an electrolytic manganese dioxide (EMD), which can be used together with ammonium and zinc chloride in zinc-carbon battery. EMD can also be found in the rechargeable manganese alkaline (ZnRAM) batteries. These applications require purity. EMD’s production process is identical to ETP (electrolytic ductile pitch): Manganese dioxide and sulfuric acid are dissolved together, with some mixtures of manganese oxide and manganesesulfate. Between the electrodes, electricity is applied. The anode is coated with the dissolved MnO2 in the solution as sulfate.

Manganese Dioxide (MnO2) Applications


Manganese dioxide is a dark or brownish solid. It is found naturally in the mineral, Pyrolusite.

The primary use for MnO2 in dry batteries is alkaline or zinc-carbon batteries.

MnO2 can also be used as a precursor to pigments and other compounds made from manganese (e.g. KMnO4). This reagent is often used for organic synthesis.

MnO2 serves as a depolarizer in dry batteries and as a catalyst in the synthesis process. It is also used in the enamel and glass industries as a colorant/decolorant as well as as an iron removal agent.

MnO2 is used in the production of special alloys, metallic manganese castings and gas masks.

The rubber industry can use MnO2 to improve the viscosity.

Chemical experiments use MnO2 as a catalyst

This is used to catalyze the breakdown of hydrogen peroxide, also known as hydrogen peroxide.

Useful for heating potassium chlorate in order to produce oxygen.

This reacts with elemental aluminium powder to make manganese through a thermite process.

You can use pigments like yellow glass or other colors.

Use hot concentrated hydrochloric acids to make chlorine.

To make potassium manganate, it reacts in the air with molten caustic potassium (potassium hydroxide).

Manganese dioxide works as a self catalyst for potassium permanganate during the decomposition of potassium permanganate.
