Fumed Silica

Introduction:　Reolosil is manufactured by controlled combustion of highly purified chlorosilanes with oxygen and hydrogen.High purity inorganic powder which aggregates are formed by 3-dimentional structure on the basis of primary particles ranging from 5 to 50 nm diameter.

Application:　Thickening and thixotropic agent for liquid resin, free flow agent for powder, reinforcing for elastomers etc.

Tetrachlorosilane STC

Introduction:　Introduction: high purity SiCL4 is manufactured by using unique technique developed by TCC, which is with a pungent odour and easy to deliquesce.

Application:　High purity STC offers many different applications such as the optical fibers, polycrystalline silicon and high purity quartz glasses.

Trichlorosilane TCS

Introduction:　Trichlorosilane(TCS) is also called silyl trichloride,silicochloroform. TCS is manufactured by controlled reaction of high purified hydrogen chloride with metal silicon in a certain temperature and pressure,through cooling、gather、rectification. TCS is easy to volatile and deliquescent. The purity of TCS is more than 99.99% and the metal impurity is less than 10ppbwt.

Application:　Quartz glass,optical fiber perform,solar cell
