Production of silica soot bodies |
摘要 |
Processes for the manufacture of a hollow cylindrical porous body of synthetic vitreous silica soot by outside vapor deposition on a mandrel are described, in which the temperature of the mandrel is controlled to be substantially constant throughout the deposition process. In preferred embodiments, the mandrel is composed of metal or metal alloy. Hollow ingots of pure or doped synthetic vitreous silica glass manufactured by such processes are also described. |
