Purpose: 

Deoxygenation and desulfurization agents in the steel industry 

Manganese silicide is mainly used as a deoxidizer and desulfurizer in steel smelting, to remove oxygen and sulfur impurities from molten steel, improve the purity and mechanical properties of steel. For example: 

Desorption: The silicon and manganese elements in manganese silicide react with oxygen in the molten steel to form low melting point oxides, which facilitate separation and improve the strength and ductility of the steel. 

Desulfurization: Manganese combines with sulfur to form manganese sulfide (MnS), reducing the negative impact of sulfur on the thermal brittleness of steel. 

Manganese silicide can also be used as an alloy additive to directly participate in the alloying process of steel, improving corrosion resistance and wear resistance. 

2. Refractory materials and high-temperature applications 

Manganese silicide and its derivatives (such as silicon manganese nitride) have important applications in the field of high-temperature materials: 

Refractory materials: used for shaped or unshaped refractory materials to enhance their high-temperature stability and corrosion resistance, suitable for industrial lining, ladle lining and other scenarios. 

3. Nitrogen increasing agent: In the production of special steels such as oriented silicon steel and high-strength steel, manganese silicide is combined with elements such as vanadium and niobium to promote nitrogen absorption and refine grain size, thereby enhancing the strength and toughness of the steel. 

4. Raw materials for the production of low-carbon ferromanganese 

Manganese silicide is a key intermediate raw material for the preparation of low-carbon ferromanganese. By adjusting the ratio of silicon and manganese, the carbon content of manganese iron alloys can be optimized to meet the production needs of different steels such as stainless steel and tool steel. 

5. Electronic materials: The application of manganese silicide in the semiconductor field is still in the research stage and can be used as a conductive layer or diffusion barrier layer. 

6. Catalyst: Based on the catalytic activity of manganese, manganese silicide may be used in chemical reactions such as oxidation or dehydrogenation. 

Packaging and storage: This product is packaged in an inert gas filled plastic bag, sealed and stored in a dry and cool environment. It should not be exposed to air to prevent moisture from causing oxidation and aggregation, which may affect dispersion performance and usage effectiveness; The packaging quantity can be provided in separate packages according to customer requirements.
