High-purity pyrogenically prepared silicon dioxide |
摘要 |
High-purity pyrogenically prepared silicon dioxide having metal contents of less than 9 ppm is prepared by reacting a silicon tetrachloride having a metal content of less than 30 ppb by means of flame hydrolysis. The silicon dioxide can be utilized for the manufacture of high-purity glasses by means of the sol-gel process, which show a high-homogenity. It can be used for the production of shaped articles, which can be used as performs for the optical fiber spinning.
