| abstract |
The invention relates to a method for producing a quartz glass body, comprising the method steps i) providing a silicon dioxide granulate made from a pyrogenic silicon dioxide powder, ii) forming a glass melt from the silicon dioxide granulate, and iii) forming a quartz glass body from at least one part of the glass melt, wherein the quartz glass body has an OH content of less than 10 ppm, a chlorine content of less than 60 ppm, and an aluminum content of less than 200 ppb. The invention further relates to a quartz glass body that is obtainable by said method. The invention further relates to a molded body and to a structure, each obtainable by further processing of said quartz glass body. |
