Abstract: A method of producing a glass body composed of two or more oxides by the flame hydrolysis technique, for example incorporating an additive or dopant oxide in a fused silica glass body. The method comprises forming a gas stream containing vapors of a compound that will hydrolyze to a glass forming oxide, e.g., silicon tetrachloride (SiCl4), nebulizing an oxide forming compound or solution of such compound to form a mist in the nature of an aerosol, and simultaneously directing the mist and gas stream into a flame of combustible gas to form and codeposit a mixture of oxides corresponding to the vaporized and nebulized compounds.

Abstract: To provide a technique with which a quartz glass jig and a doped quartz glass jig are regenerated by completely removing the impurities which are attached to the surface and the impurities which have diffused into the interior from quartz glass jigs which have been used in semiconductor production processes and then carrying out working repair and removing the contamination from the working processes as well. After use, the impurities are removed from the aforementioned quartz glass jigs in the said purification treatment process which includes a purification treatment process in which the quartz glass jigs are subjected to a purification treatment in a gaseous atmosphere which includes a halogen element at a temperature within the region above a prescribed temperature.
