421/441/553 Metallurgical Additives Use Silicon Manganese
Silicon metal is also called industrial silicon or crystalline silicon. It is silver gray with metallic luster,when be processed into powder the colour is dark gray. It has high melting point,good heat resistance and high resistivity.It is usually used in electro, metallurgy and chemical industry.It is the indispensable essential raw material in the hi-tech industry.
Product Details
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.

Applications
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. 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.
Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
