  • ANNEALED QUARTZ GLASS CLOTH AND METHOD FOR MANUFACTURING SAME
    Publication number: 20210395929
    Abstract: The present invention is an annealed quartz glass cloth that has an SiO2 content of 99.5 mass % or more, a dielectric loss tangent of less than 0.0010 at 10 GHz, and a tensile strength of 1.0 N/25 mm or more per cloth weight (g/m2). This provides an annealed quartz glass cloth that has a low dielectric loss tangent and that is also excellent in tensile strength; and a method for manufacturing an annealed quartz glass cloth by which strength recovers after a high-temperature heat treatment.
