Manganese Dioxide

Manganese dioxide is a black-brown substance that occurs naturally. Manganese dioxide, also known as pyrolusite in nature, is the most abundant of all manganese compounds. The primary resource of manganese dioxide is pyrolusite, which was used as a pigment by the ancients. By reducing manganese dioxide with carbon, impure manganese can be produced. It is the only major quadri-positive manganese compound.

Molecular Formulae- MnO2

Alternative Names- Manganese (IV) Oxide, Pyrolusite, Dioxo Manganese

Country of Origin- India

BENEFITS AND APPLICATION-

• Almost all the raw materials used in the ceramic industry to make glass contain some iron, generally in the form of ferric oxide.
• Manganese ores are not 'active' for direct use in dry cell manufacturing, and many of them must be activated by physical or chemical treatment.
• In glassmaking, it is used to eliminate the green color produced by iron impurities.
• Used as a key component in batteries. The positive electrode carbon in the Leclanche cell is surrounded by manganese dioxide and carbon.
• MnO2 is widely employed in dry cell batteries, such as alkaline batteries and zinc-carbon batteries.
• It is used as an inorganic pigment in ceramics and glassmaking, among other things.
