Abstract: A method is provided for manufacturing a synthetic silica glass. The method includes the steps of maintaining a silica glass member, which is formed using a flame hydrolysis method and having an OH group concentration of about 500 ppm to about 1300 ppm, at a predetermined holding temperature for a predetermined period of time so as to substantially relax the structure of the silica glass member. The method further includes the step of subsequently cooling the silica glass member to a first predetermined temperature at a cooling rate of about 10 K/hour or less, and thereafter, cooling the silica glass member to a second predetermined temperature at a cooling rate of about 1 K/hour or less. The method further includes the step of further cooling the silica glass member to a third predetermined temperature at a cooling rate of about 10 K/hour or less.

Abstract: This invention relates to an optical fiber having a structure that effectively reduces transmission loss and bending loss. An optical fiber according to this invention is an optical fiber mainly comprised of silica and including a core region and a cladding region covering the core region. The core region is doped with chlorine so as to have a refractive index higher than that of pure silica. The cladding region is doped with fluorine so as to have a refractive index lower than that of pure silica. The optical fiber, in particular, is characterized in that a peak value of a relative refractive index difference of the core region with respect to a refractive index of pure silica is 0.05% or more.

Abstract: In a known optical component a cylindrical glass core of synthetic quartz glass contains hydroxyl groups, a maximum 200 wt.-ppm of chlorine, and no dopant in the form of a metal oxide. The glass core is axially enveloped by a glass mantle of doped quartz glass which has a lower refractive index than the glass core. Setting out from this, in order to offer an optical component of quartz glass for broad-band transmission, especially for broad-band spectroscopy, which is characterized by low attenuation over a broad range of wavelengths, it is proposed by the invention that the core glass contain less than 5 wt.-ppm of hydroxyl groups.

Abstract: A pelletized expanded glass material is provided, which is particularly suitable as a growth support for microorganisms, especially for use in a biogas plant or an anaerobic sewage treatment plant. The production process of the invention for the pelletized expanded glass material contains the steps of: mixing a ground glass, an expanding agent and a binder to give a starting mixture. The starting mixture is pelletized to give ground glass pellet green bodies. The ground glass pellet green bodies are foamed to give expanded glass pellet particles at temperatures of 600 to 950° C. Accordingly, especially in the production of the starting mixture, minerals and or trace elements are added, which serve especially for the nutrient supply of microorganisms used in the biogas plant or the anaerobic sewage treatment plant.
