  • SiO2 shaped body which has been vitrified in partial areas, process for producing it, and its use
    Publication number: 20040118158
    Abstract: A process for producing an SiO2 shaped body which is at least partially vitrified, wherein an amorphous, porous SiO2 green body is sintered or vitrified by contactless heating by means of radiation, while avoiding contamination to the SiO2 shaped body with foreign atoms, wherein the radiation used is the beam of a laser at a subatmospheric pressure below 1000 mbar.
    Type: Application
    Filed: December 10, 2003
    Publication date: June 24, 2004
    Applicant: Wacker-Chemie GmbH
    Inventors: Fritz Schwertfeger, Axel Frauenknecht, Jens Guenster, Sven Engler, Juergen Heinrich
  • SiO2 shaped body which is vitrified in partial regions or completely, process for its production and use
    Publication number: 20030104920
    Abstract: A process for producing an SiO2 shaped body which is vitrified in a partial region or completely, in which process an amorphous, porous SiO2 preform is sintered or vitrified by contactless heating by means of laser radiation, by means of which contamination of the SiO2 shaped body with foreign atoms is avoided.
