This inorganic compound has the chemical formula MnO2, resulting in a powdery black substance or black orthorhombic crystalline form. 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, and hydrochloric acid concentrated under heating.
Manganese dioxide is a compound with an octahedral crystal structure. The oxygen atoms on the corners are the manganese atoms. The manganese is in the octahedrons. The octahedrons form a chain by connecting them together. These chains, along with other chains, are placed on top to form a tunnel-like structure. 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 as a dry battery depolarizer. 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 an oxidant, catalyst, colorant and decolorizer by the synthesis and glass industries. Manganese dioxide can be used to make metallic manganese as well as special alloys, ferromanganese casts, gasmasks and electronic material ferrites.
Manganese oxide can be used in rubber to increase viscosity, as well as in chemical experiments.
Use of laboratory equipment
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 dioxide is produced by thermite reactions between elemental aluminium powder and manganese oxide.
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.
Manganese oxide acts as an auto-catalyst in the decomposition of potassium permanganate.
