  • Process for producing polycrystalline silicon
    Patent number: 10562779
    Abstract: Deposition on a sightglass in a reactor for CVD deposition of silicon is reduced by conducting a first purge gas stream substantially parallel to the reactor end surface of the sightglass, and conducting a second purge gas stream within the sightglass tube at an angle from the sightglass surface toward the interior of the reactor.
    Type: Grant
    Filed: November 13, 2017
    Date of Patent: February 18, 2020
    Assignee: WACKER CHEMIE AG
    Inventors: Goeran Klose, Heinz Kraus, Franz Salzeder
