What material is high carbon silicon

High carbon silicon is a silicon alloy with a higher carbon content, usually between 15-20%. It is composed primarily of silicon and carbon and may contain balance elements such as sulfur, phosphorus, and carbon dioxide. High carbon silicon alloy, also known as silicon carbon alloy or ferrosilicon, is a cost-effective composite deoxidizer with deoxidation and desulfurization capabilities. In steel production, high carbon silicon is used to improve the quality of steel because it can combine with oxygen with the strong affinity of silicon and carbon to generate deoxidation products that are easy to float and eliminate. It also prevents the harmful effects of inclusions such as Al2O3 and has Certain desulfurization and dephosphorization capabilities. The weight percentage of high carbon silicon is Si: 45-68%, C: 15-20%, and the particle size is 10-50mm, 3-10mm, 0-3mm and other specifications.
