Ferrosilicon is an alloy made primarily of iron and silicon, typically containing 15% to 90% silicon. It is produced by reducing silica (silicon dioxide) in a furnace, which results in a material that is used mainly in the steelmaking industry. Ferrosilicon enhances the strength and quality of steel, making it more durable and resistant to corrosion. In addition to its role in steel production, ferrosilicon is also used in the manufacturing of cast iron and as a deoxidizer in various metallurgical processes. Its unique properties make it valuable in the production of silicon for electronics and other applications, contributing to advancements in technology.
