What are the Uses of Manganese Dioxide?


Manganese dioxide is a versatile chemical compound with the formula Mn02. It is manufactured using top-quality manganese ores with high catalytic activity, impurity-free & no additives. Manganese dioxide is widely used in a range of applications, including water treatment, battery materials, industrial organic synthesis, oxidizing agents, pigments and others. In this blog, we discuss the different uses of manganese dioxide, shedding light on its role across different industries. 


Manganese Dioxide Chemical Formula: Mn02


What is Manganese Dioxide? 


Manganese dioxide is an inorganic compound that occurs naturally as the mineral pyrolusite. It appears as a blackish or brownish solid with a crystalline structure. Manganese dioxide's remarkable physical and chemical properties make it indispensable in various industrial applications. When it comes to sourcing high-quality manganese dioxide, opt for trusted suppliers. Western Adsorbents & Catalysts is the top manganese dioxide supplier in India, offering top-quality Mn02.

What are the Uses of Manganese Dioxide? 


  • Dry-cell Batteries: One of the primary and common uses of manganese dioxide is in dry-cell batteries. The manganese dioxide manufacturers in India provide this versatile component to be used in alkaline batteries, lechanche cells and zinc carbon batteries. It is also used as a depolarizer of dry cells. 

  • Water Treatment: Mn02 is widely used for treating groundwater. It is highly effective in removing hydrogen sulphide, iron, arsenic, manganese and radium from the water. Mn02 is used as a hosting material in water treatment that works excellently with a lower backwash rate. 

  • Catalyst: Manganese dioxide is a powerful catalyst for water purification. It serves as a filtration agent via its catalytic reaction during the chemical oxidation-reduction process that helps to remove manganese, iron, radium and hydrogen sulphide. This allows for the non-oxidized iron and manganese traces to solidify and be absorbed by the manganese dioxide media. 

  • Laboratory Use: Mn02 is used as a catalyst when hydrogen peroxide is decomposed to form oxygen. It is also used as an aluminothermic reaction with elemental aluminium powder to form manganese. 

  • Steel Manufacturing: Mn02 is used in the manufacturing of steel and other alloys to enhance the quality of end products. 

  • Other Uses: It is used in the ceramic industry to make glass, and basically, all the raw materials used in glass, such as iron, are in the form of ferric oxide.


Manganese dioxide is a versatile chemical compound with excellent chemical and physical properties. From water treatment, dry batteries, steel manufacturing to oxidizing agent, Mn02 is an essential mineral in various applications.
