Verfahren und Vorrichtung zur Herstellung von Quarzglaskörpern

摘要

The invention concerns a process for producing quartz glass bodies, wherein SiO2 particles are precipitated in layers on the cylinder jacket surface of a cylindrical support (1) that rotates about its longitudinal axis, thus forming an oblong porous green body (11). The SiO2 particles are produced in precipitation burners (2), electrostatically charged in an electrical field that is maintained between the surface of the developing green body (11) and the precipitation burners (2), and then sintered in the direction of the green body (11).
