This article demonstrated a technology for producing ultra-purity silicon tetrachloride, which using the high purity SiCl4 as raw material through the method of combination ray reaction with purification. This technology could remove metal impurities and compounds impurities contained hydrogen effectively. The purity of product prepared by this technology can reach at 99.9999%, content of metal impurities can be low at 0.3PPb, meeting the requirement of industry easily. This technology has the advantages of simple process, continuous operation, and stable performance.
