Electrolytic Manganese Metal（EMM 99.5 99.7）

Electrolytic manganese metal is produced by electrolysis by obtaining manganese salt from manganese ore through acid leaching. It is a manganese product with high purity, and its main component is manganese, and its purity can generally reach 99.7% - 99.9%. In the air, the surface of electrolytic manganese metal is easily oxidized to form a layer of manganese oxide film, which can prevent the internal manganese from being further oxidized to a certain extent. It can react with acid to generate corresponding manganese salt and hydrogen.

Despite the high purity, it still contains a small amount of impurities. Common impurities include carbon, sulfur, phosphorus, silicon, iron, etc. For example, the carbon content generally does not exceed 0.02%, the sulfur content does not exceed 0.03%, the phosphorus content does not exceed 0.005%, the silicon content does not exceed 0.01%, and the iron content does not exceed 0.03%. These impurity contents need to be strictly controlled because they may have an adverse effect on the performance and application of electrolytic manganese flakes. For example, too high iron impurities may affect the alloying effect of manganese in steel.

Common size range:

Steel smelting:

When coarse-grained manganese metal flakes are used as deoxidizers and alloy additives in the steelmaking process, the dissolution rate is relatively slow. They can continuously play a deoxidizing role in molten steel, effectively remove oxygen from molten steel, and improve the purity of steel.

Manganese alloy production:

When producing high-silicon manganese alloys such as manganese silicon alloy, the use of coarse-grained manganese flakes in combination with other raw materials can better control the reaction, promote the reduction of silicon and manganese, ensure the smooth furnace condition, and help produce high-silicon manganese silicon alloys that meet the standards.

Non-ferrous metal alloy manufacturing:

When manufacturing non-ferrous metal alloys such as aluminum-manganese alloy and magnesium-manganese alloy, medium-grained electrolytic manganese are easier to add to the alloy smelting furnace, and can be quickly melted and evenly distributed in the alloy liquid, achieving effective alloying of the alloy, refining the alloy grains, and improving the strength, toughness and creep resistance of the alloy.

Chemical industry:

In some chemical reactions that require manganese as a catalyst, medium-grained electrolytic manganese flakes can provide a larger reaction contact area, making the reaction more sufficient and efficient.

Battery industry:

In zinc-manganese dry batteries, fine-grained manganese flakes can be converted into manganese dioxide after chemical treatment as a positive electrode active material. Its fine particle size can increase the contact area with the electrolyte, improve the discharge performance and capacity of the battery, and enable the battery to provide electrical energy stably for a long time.

Electronic industry:

Fine-grained EMM manganese flakes can be used to manufacture magnetic materials in electronic components. Due to its fine size, it can better meet the requirements of electronic components for material properties and help improve the performance and stability of electronic components.

Powder metallurgy:

In the field of powder metallurgy, its fine size helps to improve the fluidity and filling of the powder, so that the sintered parts have higher density and better mechanical properties, and can be used to manufacture mechanical parts, tools, etc.

Chemical reagent production:

It can be used to produce various manganese salt chemical reagents, such as manganese sulfate, potassium permanganate, etc. Fine-grained Mn metal flakes can react with acid and other reaction substances faster, improve production efficiency, and better control the reaction to ensure the quality and purity of the product.
