ABSTRACT:
A process for producing an SiO2shaped body which is at least partially vitrified, wherein an amorphous, porous SiO2green body is sintered or vitrified by contactless heating by means of radiation, while avoiding contamination to the SiO2shaped body with foreign atoms, wherein the radiation used is the beam of a laser at a subatmospheric pressure below 1000 mbar.
