Chemical-Grade Refined Silicon 2202
Form: Fine granules or crystalline blocks
Applications: Silicone production, chemical processing, high-grade aluminum alloys
Controlled Purification Process and Industrial Advantage
The Silicon Metal Grade 2202 is refined through a low-carbon, oxygen-controlled arc-furnace process, designed to achieve exceptionally high purity and stable structure. Each batch undergoes continuous temperature monitoring and multi-stage gas filtration, ensuring precise control over impurity segregation and maintaining a uniform crystalline matrix.
This material demonstrates outstanding thermal conductivity and chemical consistency, which allows it to perform reliably in both chemical synthesis and semiconductor precursor production. The optimized Fe/Al ratio minimizes unwanted side reactions and supports predictable reaction kinetics, resulting in greater conversion efficiency and higher yield rates in downstream manufacturing.
In addition, its controlled calcium and carbon levels prevent oxidation and contamination during melting, making it especially suitable for silicone polymer synthesis, aluminum refining, and electronic material preparation. Combined with ZhenAn's advanced refining facilities and automated process control, Silicon 2202 provides a stable, repeatable quality standard trusted by chemical processors, alloy producers, and electronic manufacturers worldwide.
