Poly-silicon (Polycrystalline Silicon)

It is the base material for semiconductor and solar cell. In recent years, it was estimated the boom for solar cell would increase rapidly. The manufacturing process of silicon has major two types Trichrorosilane method (Siemens method) and zinc reduction method. Torichlolosilane method predominates currently.

œ Solution by IVT
In the case of manufacturing silicon process under high pressure, zero external leakage is crucial due to the high toxic nature in the Trichlorosilane fluid. Furthermore, while transporting hard particle fluid using high verocity, in most cases, life cycle of the valves were greatly shortened by the serious damage. IVT can provide longer lasting valve with the special hard facing on the perfect round ball and metal seat.
