Metallurgical Grade Silicon Metal, commonly known as metallurgical silicon or metallurgical-grade silicon (MG-Si), plays a pivotal role in various industrial processes. This article aims to shed light on the importance of metallurgical grade silicon, for instance, its production, and its diverse applications in the metallurgical and manufacturing sectors.
Production Process: Raw materials of Metallurgical Grade Silicon Metal are primarily quartz, one of the Earth’s most abundant minerals. The production process involves the reduction of quartz (silicon dioxide) with carbon in submerged-arc electric furnaces. The reaction produces silicon and carbon monoxide, and the resulting silicon is then refined to meet the certain purity standards. Consequently, the end product is a versatile material with a silicon content typically ranging from 95% to 99.5%.
