Manganese dioxide This inorganic compound has the chemical formula MnO2, and is either a black amorphous or orthorhombic powder. Manganese dioxide can be used as a rust remover, an oxidant or in the preparation manganese sulfates.

Magnesium dioxide powder properties

Manganese oxide is not soluble in water, weak acids or bases, nitric acids, cold sulfuric acid and concentrated hydrochloric Acid.
Manganese dioxide is octahedral in structure. The oxygen atoms on the corners are the manganese atoms. Manganese is in the octahedrons. The octahedrons form a chain by connecting them together. The octahedrons are connected together to form a single or double chain. The octahedron may be either hexagonal closely packed or squarely tightly packed.

Manganese dioxide, also known as amphoteric iron oxide, is a very stable black powdery solid at room temperature. At room temperature, it is a powdery black solid. It can also be used to depolarize batteries. In the laboratory its oxidizing qualities are often used by HCl to produce chloride.

Magnesium dioxide Powder Applications

Manganese dioxide can be used to depolarize dry batteries. It is also used as a catalyst, an oxidant for synthesis and as a colourant, decolorizer and deironing agent for the glass and enamel industries. Manganese dioxide can be used to make metallic manganese as well as special alloys, gasmasks, electronic material ferrites, and ferromanganese casts.

Manganese oxide can be used as a catalyst in chemical experiments, or in the rubber and rubber products industry to increase viscosity.

Laboratory Use
Manganese dioxide can be used as a catalyst for the breakdown of hydrogen peroxide in order to produce oxygen.
The manganese oxide is used as catalyst in the decomposition of potassium chlorate.
Manganese is produced by thermite reactions between manganese oxide and aluminum powder.
Manganese oxide is used for a yellow pigment in glass, and so on.
When manganese oxide reacts with hydrochloric acid heated to a concentrated state, it produces chlorine.
When manganese oxide reacts with molten potassium hydroxide in the air, it produces potassium manganate.
In the decomposition of potassium permanganate manganese oxide acts as an auto-catalyst.
