The single crystal silicon Czochralski method is currently the main method for producing single crystal silicon, and it is also the main method for producing single crystal silicon for solar cells. The Czochralski monocrystalline silicon heat field is fabricated by finishing and assembling large-size isotropic graphite products. It includes a heater, a three-petal pot, a guide tube, an insulation cover, a crucible tray support bar, etc.
