Used as a catalyst in the decomposition of hydrogen peroxide, where it speeds up the breakdown into water and oxygen without being consumed in the reaction.

Commonly found in dry-cell batteries, such as zinc-carbon and alkaline batteries, where it acts as a cathode material and depolarizer to prevent hydrogen buildup and maintain efficient electron flow.

Employed in the glass and ceramic industries to remove unwanted green tint caused by iron impurities or to produce colored glazes and stains, typically brown, black, or purple.

Utilized in the production of ferrites for electronic components like inductors and transformers due to its magnetic properties.

Applied in water treatment processes to remove iron and hydrogen sulfide from well water or wastewater through oxidation and filtration.

Used in organic synthesis as an oxidizing agent, for example, in the production of acetic acid from acetaldehyde or the oxidation of allylic alcohols to corresponding carbonyl compounds.

Additionally, employed in the paint and coating industries as a black pigment and to enhance weather resistance.
