  • Method for forming fused quartz using deuterium
    Patent number: 7363776
    Abstract: A silica deposition tube is fused in a deuterium (D2) gas atmosphere and optionally baked in a deuterium (D2) gas atmosphere to substantially reduce the hydrogen content in the tube for decreased fiber attenuation. Alternatively, raw silica material is pre-treated in D2 gas followed by fusing of the raw silica tube in a D2 gas environment.
    Type: Grant
    Filed: October 4, 2004
    Date of Patent: April 29, 2008
    Assignee: Momentive Performance Materials Inc.
    Inventors: Larry Q. Zeng, Victor L. Lou, Frederic F. Ahlgren, Anil Raj Duggal
