QUARTZ PRODUCTS

Advantages of using quartz diversion tube

High purity - same material as quartz crucible, purity up to 99.99%.

No oxidation - compared with graphite guide tube, it will not be powdered and will not affect the carbon content of monocrystalline silicon.
Low cost - equivalent to less than 30% of graphite and tungsten draft tube.
