Product Features:

Manganese dioxide is a black amorphous powder or black orthorhombic crystal. It is a highly stable oxide of manganese, commonly found in pyrolusite and manganese nodules. Its primary use is in the manufacture of dry batteries, such as carbon-zinc batteries and alkaline batteries. It is also frequently used as a catalyst in chemical reactions or as a strong oxidizing agent in acidic solutions. Manganese dioxide is a non-amphoteric oxide (non-salt-forming oxide). It is a very stable black powdery solid at room temperature and can serve as a depolarizer in dry batteries. It is also a strong oxidizing agent that does not burn on its own but supports combustion, so it should not be stored together with flammable materials.

Product Parameters:

Product Application:

1. The product is used as a depolarizer for dry batteries, a catalyst and oxidizer in the synthesis industry, and a colorant, decolorizer, and iron remover in the glass and enamel industries.

2. Used for manufacturing manganese metal, special alloys, manganese iron castings, gas masks, and electronic materials such as ferrites.

3. Used in the rubber industry to increase the viscosity of rubber, and can also be used as a catalyst in chemical experiments.

4. Manganese dioxide is highly useful in organic chemistry. It is used in various forms for oxidation, as manganese dioxide has multiple crystalline structures. It can be produced through the reaction of potassium permanganate and manganese sulfate under different pH conditions. The brown manganese dioxide precipitate is very dry and highly active. Effective organic solvents include aromatic substances, carbon tetrachloride, ether, tetrahydrofuran, and esters. Even if the resulting products are highly active, they will not be further oxidized. Diols can be oxidized by manganese dioxide to form diketones. There are numerous other reactions involving manganese dioxide, which can be used to oxidize amines, aromatic compounds, triols, and more.

5. Used as a catalyst in the decomposition of hydrogen peroxide (hydrogen peroxide) to produce oxygen.

6. Used as a catalyst for heating potassium chlorate to produce oxygen. Elemental aluminum powder undergoes an aluminothermic reaction to produce manganese.

7. Used as a pigment, yellow glass, etc. Reacts with hot concentrated hydrochloric acid to produce chlorine gas.

8. React with molten caustic potash (potassium hydroxide) in the air to produce potassium manganate.

Packaging Introduction:

1. Sample test packaging as specified by the customer (<1kg/bag)

2. Sample product packaging (1kg/bag)

3. Standard product packaging (1kg/2kg/5kg/10kg)

Note: Inner packaging: transparent PE bag; outer packaging: vacuum-sealed aluminum foil bag. Packaging can be customized according to customer requirements.

Product Packaging:
This product is packaged with inert gas and should be stored sealed in a dry, cool environment. It should not be exposed to air to prevent moisture-induced oxidative agglomeration, which may affect dispersion performance and usage effectiveness. Packaging quantities can be provided according to customer requirements, with sub-packaging available.
