Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen eines Quarzglaskörpers beinhaltend die Verfahrensschritte i.) Bereitstellen eines Siliziumdioxidgranulats, wobei das Bereitstellen zumindest die Schritte beinhaltet: I. Bereitstellen von Siliziumdioxidpulver; und II. Verarbeiten des Siliziumdioxidpulvers zu einem Siliziumdioxidgranulat, wobei das Siliziumdioxidgranulat einen größeren Partikeldurchmesser aufweist als das Siliziumdioxidpulver, wobei das Verarbeiten folgende Schritte beinhaltet: 1) Verarbeiten des Siliziumdioxidpulvers zu einem Siliziumdioxidgranulat I, wobei das Siliziumdioxidgranulat I einen ersten Kohlenstoffgehalt wC(1) aufweist, 2) Behandeln des Siliziumdioxidgranulats I mit einem Reaktanden unter Erhalt eines Siliziumdioxidgranulat II mit einem weiteren Kohlenstoffgehalt wC(2), wobei der weitere Kohlenstoffgehalt wC(2) kleiner ist als der erste Kohlenstoffgehalt wC(1); ii.) Bilden einer Glasschmelze aus dem Siliziumdioxidgranulatund; iii.) Bilden eines Quarzglaskörpers aus zumindest einem Teil der Glasschmelze. Die Erfindung betrifft weiterhin einen Quarzglaskörper, der durch dieses Verfahren erhältlich ist. Weiterhin betrifft die Erfindung einen Lichtleiter, ein Leuchtmittel und einen Formkörper, die jeweils durch Weiterverarbeiten des Quarzglaskörpers erhältlich sind. Außerdem betrifft die Erfindung ein Siliziumdioxidgranulat II erhältlich als Zwischenprodukt des erfindungsgemäßen Verfahrens.
