Silicon metal powder is a powdered form of silicon metal, produced by crushing and sieving silicon to achieve high purity, uniform particle size, and stable chemical properties. It is widely used in industries such as metallurgy, chemicals, and electronics, with typical silicon purity ranging from 98% to 99.99%.

The main applications of silicon metal powder include:
1. Alloy Production: Silicon metal powder is a key raw material in producing ferrosilicon and other silicon-based alloys, widely used in steelmaking to enhance the strength, wear resistance, and corrosion resistance of steel.

2. Foundry Industry: Adding silicon metal powder in casting processes improves the strength and hardness of castings and enhances the surface finish of the final products.

3. Chemical Industry: Silicon metal powder serves as a raw material for producing silicon compounds, silicone oils, and resins, commonly used in the synthesis of organosilicon compounds.

4. Electronics Industry: It is essential for manufacturing monocrystalline and polycrystalline silicon, which are critical in solar cells and semiconductor devices in high-tech fields.

5. Refractory Materials: With its high-temperature resistance and anti-oxidation properties, silicon metal powder is used in refractory materials and ceramics to strengthen material durability.

200 Mesh (75 Microns):
· Application: 200-mesh Silicon Metal powder is commonly used in casting and refractory materials, with a moderate particle size that allows for uniform distribution within the matrix.
· Characteristics: Suitable for products that require moderate fineness, providing good mechanical properties and fluidity.

325 Mesh (45 Microns):
· Application: 325-mesh Silicon Metal powder, being finer, is more suited to applications requiring high dispersibility and uniformity, such as high-performance refractory materials and ceramics.
· Characteristics: With high fineness and larger surface area, it enhances the density and oxidation resistance of products, especially in materials with high strength and anti-cracking requirements.

100-150 Mesh (150-100 Microns):
· Application: This coarser grade is typically used in applications with lower requirements for filler effect and uniformity, such as general casting and welding materials.
· Characteristics: The coarser particles make it ideal for applications requiring good fluidity and filling properties, providing better thermal stability.
