Product Description:
Used as a catalyst in the decomposition of hydrogen peroxide, manganese dioxide speeds up the breakdown into water and oxygen without being consumed in the reaction. It is commonly employed in laboratories for oxygen generation. In dry-cell batteries, such as alkaline and zinc-carbon batteries, it acts as a depolarizer, preventing voltage drop by reducing polarization at the cathode. It is also used in the production of ferrites for electronic components due to its magnetic properties. In glass and ceramic manufacturing, it serves as a colorant and decolorizer, helping to remove green tints caused by iron impurities or adding black, brown, or purple hues. Additionally, it plays a role in the oxidation of organic compounds in chemical synthesis and environmental remediation, such as breaking down pollutants in water treatment.
