Product Description
Product information:
Manganese dioxide, also known as "manganese peroxide", "black manganese oxide", is an oxide of tetravalent manganese, chemical formula is MnO2, fHm(298K)=-520.71kJ/mol, melting point 847ºC, density 5.026g/cm3, natural The product exists in pyrolusite, black orthorhombic crystal or black-brown powder, with tetrahedral lattice, is an amphoteric manganese oxide, insoluble in water and nitric /acid. In hot concentrated sulfuric acid, oxygen is released to form manganese sulfate. Chlorinated in hydrochloric/ acid to form manganese chloride. It is co-melted with caustic Chemicalbook alkali and oxidant, and releases carbon dioxide to form permanganate. Manganese dioxide is a strong oxidant, and friction or co-heating with organics or other oxidizable substances (such as sulfur, sulfide and phosphide, etc.) can cause combustion and explosion. This product exhibits reducing properties when interacting with strong oxidants (such as hydrogen /peroxide). In the air, MnO2 is heated to above 480 °C and converted into Mn2O3, and above 900 °C into Mn3O4. It is widely used in steelmaking, and in making glass, ceramics, dry batteries, etc.
