About
Silicon Metal 553 Grade is a refined metallurgical silicon containing 98.5% minimum silicon purity with controlled levels of iron (0.5%), aluminum (0.5%), and calcium (0.3%). Sourced from high-grade quartz and processed in electric arc furnaces at temperatures exceeding 2000°C, this industrial-grade silicon serves as a critical raw material for aluminum alloy production, chemical synthesis, and semiconductor manufacturing. The 553 designation indicates its precise impurity specifications, making it suitable for applications requiring consistent metallurgical properties. Makers and manufacturers purchase this grade for aluminum casting, silicone polymer production, and as a deoxidizing agent in steel manufacturing. Its controlled composition ensures reliable performance in high-temperature applications and chemical processes. The material typically comes in lump form ranging from 10-50mm, offering excellent handling characteristics for industrial processing. This processed silicon represents a key intermediate material in the supply chain between raw quartz mining and finished silicon-based products.
