Silicon Metal Lump Properties
Our industrial silicon or silicon metal lumps come in irregularly shaped chunks. These chunks are silvery gray or dark grey with a metallic luster. These lumps are made up of quartz (SiO2) meaning they can be processed to extract high purity silicon. The material features a high fusing point, outstanding heat resistance, and high resistivity. The high purity silicon extracted from this product is a vital material in the production of electronics components.
Silicon Metal Lump Applications
The silicon metal lumps can be further processed into higher purity silicon and then used as an additive in aluminum alloy ingot smelting, steel production, aluminum alloy production, and electronic component production.

Applications of Silicon metal Granule and Powder
1. Industrial silicon granule & powder is widely used in the production of refractory materials and metallurgical applications due to its high temperature resistance, wear resistance, and oxidation resistance. Some examples of its application are furnace walls, kilns, and kiln furniture.
2. In organic silicon chemical operations, granular & powder silicon metal is a base material used in the synthesis of organic silicon products. It is often used to manufacture silicon monomers, silicone oils, and silicone rubber preservatives. As an additive, this product provides a significant increase in temperature resistance, electrical insulation, corrosion resistance, waterproofness, and many more highly valuable properties.
3. Some of the more valuable applications of silicone metal involve using silicon wafers to produce integrated circuits and other electronics components. The granule & powder undergoes a drawing process, turning it into monocrystalline silicon wafers. High-tech industries are essentially driven by silicon.
4. In the metallurgical casting industry, industrial silicon metal is an additive for nonferrous alloys and alloying agents in silicon steel in order to greatly enhance the hardness of the finished steel products. Silicon granules are also used as a metal reducing agent for modern ceramic alloys, providing additional hardness and heat resistance.
