  • Device and method for the removal of polycrystalline silicon rods from a reactor
    Patent number: 10974216
    Abstract: A device for removing polycrystalline silicon rod pairs from a Siemens reactor has a body dimensioned to fit over a single rod pair. Once the rod pair is within the body, the body and enclosed rod pair is removed.
    Type: Grant

  • Method for deinstallation of rod pairs of polysilicon produced by the Siemens process
    Patent number: 10301181
    Abstract: Polycrystalline silicon is produced by depositing polycrystalline silicon onto U-shaped slim rods, deinstalling at least one polycrystalline silicon rod pair from the reactor, removing graphite residues from the electrode-side ends of the polycrystalline silicon rods of the polycrystalline silicon rod pair, and comminuting the polycrystalline silicon rods into rod pieces or into chunks, wherein prior to deinstallation of the polycrystalline silicon rod pairs from the reactor, the polycrystalline silicon rod pairs are at least partially with a plastics material bag made of a plastics material film having a thickness of more than 150 ?m, wherein the plastics material bag comprises weights at its opening. The invention further relates to a polycrystalline silicon rod pair which has a rod diameter of 190 mm or more and is covered by a plastics material bag made of a plastics material film having a thickness of more than 150 ?m.

  • Method for producing polycrystalline silicon
    Patent number: 10077192
    Abstract: Production of highly pure comminuted polycrystalline silicon from polycrystalline silicon rods produced by the Siemens process is facilitated by removal of graphite residues from the electrode ends of the rods by removing the contaminated end portions by means of mechanical impulses.
