From this starting point, a method is provided for achieving nitrogen doping in quartz glass with as high a fraction of chemically bound nitrogen as possible. This object is achieved according to the invention in that a nitrogen oxide is used as the nitrogen-containing reaction gas, and that a SiO2 base product is used that in the hot process has a concentration of oxygen deficient defects of at least 2×1015 cm−3, wherein the SiO2 base product comprises SiO2 particles having an average particle size in the range of 200 nm to 300 μm (D50 value).

    摘要: The invention relates to a previously known method for producing synthetic silica glass, comprising the following steps: a gas stream containing a vaporizable initial substance, which can be converted into SiO2 by means of oxidation or flame hydrolysis, is formed; the gas stream is delivered to a reaction zone in which the initial substance is converted so as to form amorphous SiO2 particles; the amorphous SiO2 particles are deposited on a support so as to form an SiO2 layer; and the SiO2 is vitrified during or following deposition of the SiO2 particles in order to obtain the silica glass. The aim of the invention is to create an economical method for producing synthetic silica glass, which is characterized by a favorable damaging behavior towards short-wave UV radiation while being particularly suitable for producing an optical component used for transmitting high-energy ultraviolet radiation having a wavelength of 250 nm or less. Said aim is achieved by using a mixture of a monomeric silicon compound containing a singular Si atom and an oligomeric silicon compound containing several Si atoms as an initial substance, provided that the oligomeric silicon compound in the mixture contributes less than 70 percent to the total silicon content.

    摘要: In a known process for producing a quartz glass cylinder, a porous soot tube, which is sintered to form the quartz glass cylinder, is produced by depositing SiO2 particles on an outer cylindrical surface of a support, which rotates about the longitudinal axis thereof and has a layer of silicon carbide (SiC layer). In order on this basis to specify a support having a high resistance to fracture, which firstly can easily be removed and which secondly presents a low risk of contamination for the soot body, the invention proposes that the SiC layer is treated at a high temperature in an oxygen-containing atmosphere before the SiO2 particles are deposited, in such a manner that an SiO2 protective layer having a thickness of at least 0.1 μm is produced by oxidation.

    摘要: In a known method for drawing a tubular quartz glass strand, a crucible is fed with SiO2-containing start material, the start material is softened in the crucible and, as a softened quartz glass mass, is drawn vertically downwards as a tubular quartz glass strand along a drawing axis through an annular gap between an outer member and an inner member, which is arranged in a through hole of the outer member, of a drawing nozzle provided in the bottom area of the crucible. To improve the known method with respect to less inhomogeneity in the drawn-off tubular strand and thereby to permit the manufacture of homogeneous, defect-free hollow cylinders of quartz glass by drawing from the melt, it is suggested according to the invention that the inner member of the drawing nozzle, viewed in the direction of the drawing axis, is held suspended and radially movable inside the through hole of the outer member, and that the annular gap of the drawing nozzle has a longitudinal section “L” in which its cross-sectional nozzle area is reduced in size from the top to the bottom.
