    Abstract: An ultra-high pressure discharge lamp in which the disadvantage of the reduction of the illuminance maintenance factor due to formation of blackening and milky opacification in the discharge vessel and the disadvantage of formation of cracks in the discharge vessel is eliminated by the discharge vessel being made of a silica glass that contains 0.1 ppm by weight to 290 ppm by weight hydrogen. Further advantages are obtained by the silica glass having a content of OH radicals that is at most 1 ppm by weight and a content of aluminum in a range of 2 ppm by weight to 30 ppm by weight.

    Abstract: The invention relates to a silica yarn and to woven or nonwoven fabrics produced from said yarn, which comprises 30 to 1500 ppm by weight of aluminum and 10 to 200 ppm by weight of titanium in oxidized form, the sum of the mass of the chemical elements different from Si and 0 being less than 5000 ppm by weight, the following elements being absent or present in a very small quantity: boron, sodium, calcium, potassium and lithium. The fabrics comprising this silica yarn have an excellent high-temperature withstand and thus retain their flexibility for a long time at above 600null C. They are useful especially in uses requiring good high-temperature flexibility, such as for furnace seals.

    Abstract: Optical quality glass having a selected refractive index is produced by a two stage drying process. A gel is produced using sol-gel chemistry techniques and first dried by controlled evaporation until the gel volume reaches a pre-selected value. This pre-selected volume determines the density and refractive index of the finally dried gel. The gel is refilled with solvent in a saturated vapor environment, and then dried again by supercritical extraction of the solvent to form a glass. The glass has a refractive index less than the full density of glass, and the range of achievable refractive indices depends on the composition of the glass. Glasses having different refractive indices chosen from an uninterrupted range of values can be produced from a single precursor solution.

    Abstract: To inhibit, or at least sharply attenuate, fluorescence of a quartz-glass velope (10) surrounding a light source (11), such as a halogen incandescent lamp, a high-pressure discharge lamp, or the like, when the quartz glass is subjected to ultraviolet (UV) radiation from the light source, and has been doped with a UV radiation absorbing material, typically a cerium, or cerium-titanium doping, the quartz-glass envelope is additionally doped with barium and boron. The barium/boron in the doping is, preferably, present in quantities of between about 0.008 and 1.25%, by weight, with reference to the undoped quartz glass. Barium metaborate can be used, optionally together with praseodymium to attenuate the fluorescence. Preferably, barium and boron form a combined doping substance with cerium, in form of a cerium aluminate and metaborate, added to the starting material for the quartz glass, and before the quartz glass is fused from quartz sand or pulverized quartz crystal.
