Product Description
Silicon metal powder, also known as industrial silicon powder, is processed from high‑quality silicon metal lumps. The powder appears silver‑grey or dark‑grey with certain metallic luster. Boasting a high melting point, excellent heat resistance and high resistivity, it delivers superior anti‑oxidation performance. Referred to as “industrial monosodium glutamate”, it is an indispensable basic raw material for many high‑tech industries.
Applications
1. Silicon metal powder is widely used in refractory materials and powder metallurgy to improve high-temperature resistance, wear resistance and oxidation resistance of finished products. Its end-products are extensively adopted in steel-making furnaces, kilns and kiln furniture.
2. In the organosilicon chemical industry, silicon metal powder serves as the basic raw material for organosilicon polymer synthesis. It is used to produce silicon monomers, silicone oil, silicone rubber and preservatives, so as to endow products with improved high-temperature resistance, electrical insulation, corrosion resistance and water-repellent properties.
3. Single crystal silicon can be drawn from silicon metal powder. Further-processed silicon wafers are widely applied in high-tech sectors as essential raw materials for integrated circuits and electronic components.
4. In the metallurgy and casting industry, silicon metal powder acts as an additive for non-ferrous alloys and alloying agent for silicon steel to enhance the hardenability of steel. It can also work as a reducing agent for certain metals and be used for new ceramic-alloy materials.
5. Featuring low impurity content and stable reaction activity, silicon metal powder is a premium core raw material for manufacturing high-quality silica sol. It enables synthesis of high-purity silica sol products with uniform particle size, strong adhesion and outstanding stability.
6. Silicon metal powder is the core raw material for silicon-carbon composite anode materials of lithium-ion batteries. It can significantly boost battery energy density, charge-discharge efficiency and cycle life, and make up for the capacity shortcomings of conventional anode materials. It is widely used in new-energy fields including power batteries, energy-storage batteries and digital lithium-ion batteries.
7. With outstanding sintering activity, silicon metal powder can be used to fabricate high-performance structural and functional ceramics such as silicon carbide, silicon nitride and silicides. It greatly elevates the material’s performance in high-temperature resistance, wear resistance, corrosion resistance and thermal-shock resistance. It finds broad applications in precision ceramic components, high-temperature kiln furniture and wear-resistant parts for high-end equipment.
