Product performance
Manganese dioxide (in the form of pyrolusite in nature), physical properties: black amorphous powder, or black rhombic crystal, solubility: insoluble in water, weak acid, weak base, nitric acid, cold sulfuric acid, soluble in hot concentrated hydrochloric acid to produce chlorine.
Application direction
1. Mainly used as depolarizer in dry batteries. It is a good decolorizer in the glass industry, which can oxidize the low price iron salt to high iron salt, so that the blue-green color of the glass turns to weak yellow.
2. It is used to make manganese zinc ferrite magnetic materials in the electronic industry. In the steel making industry, it is used as the raw material of ferromanganese alloy and as the heating agent in the casting industry. The gas mask is used as an absorbent for carbon monoxide.
3. In the chemical industry, it is used as an oxidant (such as purplish red synthesis), a catalyst for organic synthesis, and a desiccant for paints and inks. It is also used as a combustion supporting agent in the match industry, as a raw material for glaze medicine of ceramics and enamel and manganese salt. It is also used for fireworks, water purification, iron removal, medicine, fertilizer, fabric printing and dyeing, etc.
Storage conditions
This product should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time to prevent moisture and agglomeration, affecting the dispersion performance and use effect. In addition, it should avoid heavy pressure and be transported as ordinary goods.
