Silicon Metal 421 is a high-purity chemical-grade industrial silicon (Si ≥ 99%, Fe ≤ 0.4%, Al ≤ 0.2%, Ca ≤ 0.1%), produced by smelting quartz and carbon in submerged arc furnaces.
It primarily serves as a key raw material in the production of organosilicon , polysilicon for solar photovoltaic panels, and aluminum alloys to enhance strength in automotive and aerospace components.
The material itself is chemically stable and inert under normal conditions, offering virtually unlimited shelf life with no degradation over time when stored in dry environments.
Downstream applications demonstrate excellent longevity: solar PV panels typically last 25-30 years (often with performance warranties), while organosilicon products, like silicone sealants and rubbers, can endure 10-50 years or more, resisting heat, UV exposure, and weathering.
