High Grade Silicon Metal With Different Types

High-grade silicon metal is categorized by purity and applications, primarily as Metallurgical Grade Silicon (MG-Si), Solar Grade Silicon (SoG-Si), and Electronic Grade Silicon (EG-Si). Metallurgical grade is the most common, with typical grades including 553, 441, and 3303, and is used for aluminum alloys, steel, and chemical precursors. SoG-Si boasts ~6N (99.9999%) purity for solar cells, while EG-Si reaches ~9N (99.9999999%) purity and is essential for semiconductors and integrated circuits.

High-purity specialty silicon includes single-crystal silicon and polycrystalline silicon. Single-crystal silicon has an orderly atomic arrangement and a purity of ≥99.9999%. It has excellent electrical properties and is used in integrated circuits, chips, and high-efficiency solar cells. Polycrystalline silicon, composed of multiple small crystals, has a purity of approximately 99.999% and is relatively low-cost. It is primarily used in photovoltaic solar panels and mid- and low-end electronic components.
