SiCl4 Is Important Inorganic Silicon Compound

With the rapid development of communication technology and network technology, optical fiber communication has a large communication capacity. The advantages of good security performance and low transmission loss have become the main body of contemporary communication. At present, SiCl4 is mainly used to prepare fiber prefabricated rods by chemical vapor deposition. The purity of SiCl4 directly affects the quality of fiber raw materials. At present, silicon tetrachloride contains Si, H2, Cl, Si, H, Cl, Ni, Cr, B, P, Cu and other metal chlorides. For the optical fiber industry, these hydrogen-containing impurities and metal impurities will increase the absorption loss of light in optical fiber transmission due to the large vibration absorption of photons. When silicon tetrachloride is used to produce optical fiber, silicon tetrachloride must be purified by removing these impurities. At present, the removal process of silicon tetrachloride mainly includes distillation method, adsorption method, compound method and so on.
