    Abstract: The invention provides a process of obtaining a gradient index type of optical element with profiles of first and second metal component concentrations by the sol-gel method. The process of fabricating a gradient index type of optical element comprises steps of dipping a silicon component-containing wet gel prepared by the sol-gel method in a solution containing an alkoxide of at least one metal component selected from a first group consisting of Ti, Nb, Ta, and Zr or a derivative thereof to thereby impart to the wet gel a concentration gradient with a concentration of the first metal component decreasing from a periphery to a center of the wet gel, allowing at least one metal component selected from a second group consisting of Ba, La, Y, Gd, Sr, Ca, and Zn to be dissolved out of the wet gel to thereby impart to the wet gel a concentration gradient with a concentration of the second metal component increasing from the periphery to the center of the wet gel, and drying, and firing the wet gel.

    Abstract: Quartz glass of high thermal stability is produced from a SiO.sub.2 solution or sol which is substantially free of alkali and alkaline earth metal oxides and contains chromium and/or manganese in about 0.05 to 20% by weight of the SiO.sub.2 expressed as Cr.sub.2 O.sub.3 and Mn.sub.2 O.sub.3. The quartz glass upon heating above 1100.degree. C. forms cristobalite having an average crystallite size of about 100 to 500 A. Articles therefrom retain their physical and mechanical properties at high temperatures. The materials are suited for producing fibers by the usual methods of spinning from solutions or sols and, as such, or as fibers they are suited for use in reinforcement and insulation and in making flameproof textiles.

    Abstract: An electric lamp comprises a light source within a glass envelope adapted to operate at temperatures above 800*C. under pressures ranging up to 100 atmospheres. The lamp may be a tungsten halide incandescent type or a discharge type such as a mercury vapor or metal halide lamp. The envelope is composed of a fused silica glass containing, on a cation mole percent basis, 0.01-1.0% of an additive selected from the group consisting of SnO2, GeO2, Fe2O3, WO3, MoO3 and Ta2O5.

    Abstract: Glass filters and their use in controlling transmission of radiation is disclosed. The filters have a sharp transmission cut off within the ultraviolet region of the spectrum and also withstand high temperatures and severe heat shock. They are produced from a fused silica glass having a composition consisting essentially of silica and 1-25 percent R2O5 wherein the R2O5 consists of 0-5 percent Nb2O5 and/or 0-25 percent Ta2O5. The transmission cut off may be shifted across the ultraviolet transmission range by varying the amount of additive.
