Abstract: In a known method for producing quartz glass that is doped with nitrogen, an SiO2 base product is prepared in the form of SiO2 grains or in the form of a porous semi-finished product produced from the SiO2 grains and the SiO2 base product is processed into the quartz glass with the nitrogen chemically bound therein in a hot process in an atmosphere containing a reaction gas containing nitrogen. 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).

Abstract: A device and method is disclosed for manufacturing optical fiber preforms utilizing microwave plasma assisted chemical vapor deposition. Precursor gas is introduced to the face of a vertically mounted dielectric rod, and a plasma is struck by means of simultaneous excitation of an E01 type wave and an H type wave with rotating linear polarization. The silica rod is positioned so that its face is at the bottom of the tube. Precursor gas is delivered from a position below the face of the silica rod, and microwave energy, which travels through the rod to the rod face, is delivered from a source positioned above the rod. With this configuration, a uniformly dense plasma localized on the face of the rod can simultaneously deposit both a pure or doped core and a doped cladding. It is also useful for creating waveguides, preform cores for use as substrates in creating optical fiber preforms, capillaries and ceramic rods.

Abstract: A number of unique processes are disclosed for manufacture of sintered high-purity quartz glass products in which a shaped silica body or preform is made from an aqueous slurry of micronized silica particles by gel casting, slip casting or electrophoretic deposition. The silica particles may comprise a major portion by weight of crystalline silica. In one embodiment of the invention the sintered quartz glass is transparent, substantially bubble-free and suitable for scientific or optical uses. In another embodiment the porous silica preform is fired in steam to increase the hydroxyl content and then nitrided in a nitrogen-hydrogen reducing atmosphere. A minute amount of chemically-combined nitrogen in the high-purity quartz glass is sufficient to provide a tremendous improvement in physical properties and an incredible increase in the resistance to devitrification.
