- Commodity name: Quartz guide tube
Photovoltaic industry design of monocrystalline silicon refining need to use the main supporting products, replace graphite devices.
Quartz split guide tube(Including two parts: quartz cover plate & quartz inner guide)
Photovoltaic industry design of monocrystalline silicon refining need to use the main supporting products, replace graphite devices. Used to play the role of purification when drawing single crystal silicon rod. The existing products are in a split situation.
Defects:
There is always a gap at the junction between the quartz cover plate and the quartz inner guide. Even if the gap of the product is very small in the initial stage, it will become larger with the use of the product;
During the drawing process of monocrystalline silicon rod, the external environment or other thermal insulation materials (such as carbon felt) used for heat insulation will volatilize for a long time with the increase of temperature. Micro-and nano-level impurities will flow along the gap with argon gas during the drawing process, and finally adhere to the surface of the silicon liquid or even enter the silicon liquid, causing pollution to affect the quality of the final silicon rod and silicon wafer.
