More Information
Summary:The invention relates to a process for the preparation of a quartz glass body comprising the process steps (i.) Providing a silicon dioxide granulate, (ii.) Making a glass melt out of silicon dioxide granulate in an oven and (iii.) Making a quartz glass body out of at least part of the glass melt, wherein the oven comprises a standing sinter crucible. The invention further relates to a quartz glass body which is obtainable by this process. The invention further relates to a light guide, an illuminant and a formed body, which are each obtainable by further processing of the quartz glass body.
