What does manganese dioxide mean?
Manganese dioxide can be described as a solid that is blackish or brown. It is manganese’s stable oxide. This compound can often be found in the pyrolusite or manganese nudules. It is not soluble or soluble with water, weak acid, weak base, or cold sulfuric acid. However, when it has been heated to make chlorine gas, concentrated hydrochloric can dissolve the substance.
Prepare manganese dioxide
The raw materials for the preparation of manganese oxide were natural minerals pyrolusite, manganese carbonate, and high temperature manganese sulfurate. Leaching, removal of iron, neutralization and heavy metal removal are some of the steps involved in the preparation manganese solution. Following high temperature electrolysis the crude product is obtained. The qualified crystal is then prepared by stripping and grinding.
Application of manganese oxide
Useful for depolarizing dry cells and as catalyst and oxidant in the synthesis and glass industries. This is used for the manufacture of manganese metals, ferro-mangannese castings, ferro-mangannese special alloys, and gas masks. It can also be used in chemical experiments as a catalyst.
