GB/T 45823-2025
ActiveHigh purity sand applied inside quartz crucible for photovoltaic monocrystalline silicon growth
光伏单晶硅生长用石英坩埚高纯内层砂
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging for high-purity sand used as the inner layer of quartz crucibles in photovoltaic monocrystalline silicon growth. It is applied in the manufacturing of quartz crucibles for the Czochralski (Cz) process, ensuring the inner sand layer minimizes impurities that could contaminate the molten silicon. The standard is critical for quality control in the photovoltaic industry, particularly for producers of high-efficiency monocrystalline silicon ingots and wafers.
