In the photovoltaic industry, thermal fields are indispensable consumables. While graphite materials have excellent high temperature resistance, good electrical & thermal conductivity, so they are widely used in the photovoltaic industry to produce thermal field graphite parts. In the czochralski single crystal furnace, commonly used thermal field graphite parts include crucibles, insulation barrels, and protective plates. In the polycrystalline casting furnace, commonly used thermal field graphite parts include casting dies & molds, casting trays, and insulation barrels. The function of these graphite parts is to support and protect monocrystalline or polycrystalline silicon, to ensure the stability and purity of the molten liquid during the preparation process. Meanwhile, these thermal field graphite parts have excellent corrosion resistance and mechanical strength, and can work stably in high temperature and harsh environments for a long time.
The thermal field system is a key device for preparing monocrystalline silicon and polycrystalline silicon. Photovoltaic thermal field graphite parts have important applications in czochralski single crystal furnaces and polycrystalline casting furnaces. For example, graphite crucibles can carry and protect quartz crucibles to ensure the stability and purity of the molten liquid during the preparation process. The insulation barrel can maintain the temperature of the molten liquid to ensure the stability of the temperature during the growth process of monocrystalline silicon or polycrystalline silicon. The protective tray can protect other parts of the thermal field system to ensure the stability and lifespan of the thermal field system.
