Products Description
Silicon slag mainly comes from the refining process of silicon ore and is the residue left after refining. Silicon slag can be classified according to its source and use, such as industrial silicon slag, solar silicon slag, semiconductor silicon slag, etc. In addition, it can also be subdivided according to silicon content, particle size, etc. Silicon slag has a complex structure and is acidic after water immersion, with a pH value of less than 1 and a solid content of about 20%. Due to the chemical reactions that occur during the production process, silicon slag also contains silicate products such as metasilicic acid, orthosilicic acid, dipetasilicic acid and triorthosilicic acid, as well as compounds such as sodium silicate.
Silicon slag has a wide range of applications in many industries. Silicon slag can be used as an admixture for cement to improve the physical properties and durability of cement and prepare high-performance cement. As an admixture for concrete, silicon slag can increase the strength and durability of concrete. It is particularly suitable for preparing high-strength concrete and used in construction projects to prepare high-quality concrete structures, such as high-rise buildings, bridges, tunnels, etc. Silicon slag can also be used to make building materials such as blocks to improve the overall performance of the material. In the process of steel smelting, silicon slag can be used as a desulfurization and deoxidizer to effectively remove impurities in steel and improve the quality of steel. Silicon slag can also be used as a carrier in the metallurgical industry to produce alloy materials such as silicon calcium and ferrosilicon. Silicon slag can be used to produce chemical raw materials such as diatomaceous earth. Through further processing, silicon slag can also be used to produce silane and other organosilicon compounds, providing important raw materials for the chemical industry.
Silicon slag has certain adsorption properties and can be used in wastewater treatment to remove harmful substances in wastewater. Silicon slag can also be used for soil improvement to improve soil fertility and air permeability. Silicon slag has other applications in the field of environmental protection, such as reducing seawater pollutants. Silicon slag can be used as an additive for casting materials to improve the quality and performance of castings. Silicon slag can be used as a filler material for road construction to improve the stability and durability of the road. Silicon slag can be used as one of the raw materials for glass manufacturing to improve the hardness and transparency of glass.
