Manganese(II,III) Oxide (Mn3O4) MicroPowder (Mn3O4, Mn >70%,APS: 2.5 um)

Manganese Oxide MicroPowder

Manganese oxide powder is an inorganic compound with the formula MnO2. This blackish or brown solid is naturally produced as the mineral pyrolusite, which is the main manganese mineral. Manganese oxide is used as a dye and bleach in glass, whiteware, enamels, and ceramics. It is also used in batteries and mixes of electronic cathodes.

Applications:

In Battery Technologies:

Lithium-Ion Batteries: Manganese oxide micro-powder is a key component in the production of cathodes for lithium-ion (Li-ion) batteries. Manganese oxide is used to make lithium manganese oxide (LiMn₂O₄), which is one of the most common cathode materials for Li-ion batteries, especially in electric vehicles (EVs) and energy storage systems. The high surface area of micro-powder increases the capacity and cycling stability of the batteries.

Zinc-Manganese Batteries: Manganese oxide is used as a cathode material in alkaline batteries and zinc-carbon batteries. It enhances battery performance, ensuring better charge retention and higher energy output.

In Catalysts and Chemical Reactions:

Catalysts for Industrial Processes: Manganese oxide is used as a catalyst or catalyst support in various chemical reactions, such as in the production of hydrogen peroxide (H₂O₂), epoxidation reactions, and auto exhaust purification (to reduce toxic emissions). Its high surface area and catalytic properties make it an effective material for these processes.

Environmental Catalysts: Manganese oxide is used in catalytic converters for the automotive industry. It helps in the oxidation of carbon monoxide (CO), hydrocarbons, and nitrogen oxides (NOx) to harmless gases like carbon dioxide and nitrogen. This application is important for reducing air pollution from vehicles.

In Electronics and Conductive Materials:

Electrodes in Supercapacitors: Manganese oxide micro-powder is used in the production of electrodes for supercapacitors due to its high surface area, conductivity, and electrochemical properties. It enhances the energy density and charge-discharge cycles of the supercapacitors, which are used in energy storage systems, portable devices, and hybrid electric vehicles.

Semiconductor Materials: Manganese oxide is also explored as a semiconductor material in various electronic devices due to its unique electrical properties.

In Ceramics and Glass Manufacturing:

Pigments: Manganese oxide is used as a colorant or pigment in ceramics and glass. It imparts a brownish-black or purple color to ceramic glazes and glass products. It is used in the production of artistic ceramics, tile glazes, and colored glass.

Ceramic Capacitors: Manganese oxide micro-powder is sometimes used in the manufacturing of ceramic capacitors, where it helps to improve dielectric properties and thermal stability.

In Water Treatment:

Water Purification: Manganese oxide is used in water treatment processes to remove iron, manganese, and sulfur from drinking water. It can also help to oxidize contaminants and improve the overall quality of water by removing impurities and heavy metals.
