Purpose:

1. Steel metallurgy and alloy additives

Deoxygenation and alloying in steelmaking: Manganese carbide is used as a deoxidizer and alloying additive to adjust the carbon and manganese content in steel, improve its strength, hardness, and wear resistance, and is widely used in the manufacture of high manganese steel (such as Hadfield steel).

Improving the performance of cast iron: Adding manganese carbide during the casting process can refine the grain size, enhance the toughness and impact resistance of cast iron.

2. Hard alloy and wear-resistant materials

Hard alloy components: combined with tungsten carbide (WC), cobalt (Co), etc., used to manufacture wear-resistant tools and mining machinery components (such as drill bits, cutting tools), but with a smaller application scale than titanium carbide or tungsten carbide.

Surface strengthening coating: By using thermal spraying or surfacing technology, manganese carbide is applied to the surface of mechanical components to enhance wear resistance and corrosion resistance.

3. Welding materials

Welding rod and wire coating: Manganese carbide, as a component of the welding rod coating or wire coating, can improve the hardness and wear resistance of the weld seam, especially when repairing worn parts.

4. Battery materials: Negative electrode materials for lithium-ion batteries:

Manganese based compounds (such as Mn∝ O ₄) have applications in batteries, while the research direction of manganese carbide includes potential candidates as negative electrode materials, improving conductivity and cycling stability through carbon composite structures.

5. Catalysis and Chemical Industry

Catalyst carrier or precursor: Manganese carbide can be used as a carrier in high-temperature catalytic reactions, or as a manganese based catalyst generated through carbon thermal reduction reactions, for processes such as synthesis gas conversion and methane reforming.

Corrosion resistant coating: Coating manganese carbide based materials on the surface of chemical equipment to enhance acid and alkali corrosion resistance.

6. Nuclear Industry and Radiation Protection

Neutron absorbing material: Manganese element has neutron absorption ability, and manganese carbide may be used as a neutron shielding or control material in nuclear reactors.

7. Ceramic reinforcement phase: Adding manganese carbide particles to ceramic matrices such as alumina and silicon nitride can improve the material's thermal shock resistance and fracture toughness.

8 High temperature structural materials:

Manganese carbide can be used to manufacture high-temperature furnace components due to its high temperature resistance (melting point of approximately 1520 ° C) in an inert atmosphere or vacuum environment.

9. Research on magnetic materials:

Manganese compounds often have magnetism, and manganese carbide has exploratory applications in magnetic composite materials or magnetic recording materials.

Storage method: This product should be sealed and stored in a dry and cool environment. It should not be exposed to air for a long time to prevent moisture from causing aggregation, affecting dispersion performance and usage effect. In addition, it should be avoided from heavy pressure and not in contact with oxidants. It should be transported as ordinary goods.
