Abstract:
Suspensions of fumed oxides, e.g. fumed silica, are prepared in non-aqueous media and the suspensions are used to cast shapes for glass or cermic products. The suspensions are destabilized prior to casting with an added gelling agent, cast before gelation, and then gelled, dried and, optionally, sintered to clear glass or void-free ceramic products.

Abstract:
The invention relates to a method for producing a doped SiO 2 slurry in which an SiO2 suspension is brought into interaction with at least one doping solution, wherein the SiO2 suspension and/or the doping solution act on one another in the form of an atomised spray, the average droplet diameter of which is in the range between 10 μm and 100 μm. The invention further relates to the use of an SiO2 slurry doped by the atomised spray method for the production of doped quartz glass, particularly for the production of laser-active quartz glass.

Abstract:
Es wird ein Verfahren zur Herstellung von Glaskörpern aus dotiertem Quarzglas durch Flammenhydrolyse angegeben, bei dem mittels eines einzelnen Brenners (14), dem Brennstoff und Precursoren zur Bildung des Glases zugeführt werden, ein Formling (24) auf einem Target (28) erzeugt wird. Das so hergestellte dotierte Quarzglas zeichnet sich durch eine geringe Defektdichte und eine verringerte Schlierendicke aus. Vorzugsweise wird der Formling (24) anschließend zu einem zweiten Formling umgesenkt wird, der eine größere Breite und geringere Höhe als der erste Formling aufweist. Dadurch können die Defektdichte und die Schlierendicken weiter reduziert werden (Fig. 1).
