Of the alkali metals, Na and Li are preferred and of the intermediate, Zr, Ti and Ge are preferred.

Abstract: Admixture of unsaturated polyester and finely ground powder particles of soda-containing silicate glass, preferably soda-lime-silicate glass, e.g. below about 40 mesh and in an amount of between about 1 to 60% based on the weight of the polyester-glass particle admixture, providing improved properties in the ultimately cured resin at lower material costs and having special application as a composition for use in fabricating fibrous glass (i.e. fiber-glass) reinforced plastics composite products.

Abstract: The present invention is concerned with the preparation of hydraulic cements, demonstrating high mechanical strength, long term resistance to attack by moisture, and virtual freedom from creep, from glass powders consisting essentially, expressed in terms of mole percent on the oxide basis, of about 60-76% SiO.sub.2, 15-30% K.sub.2 O, and 2-15% total of at least one metal oxide selected from the group of 0-10% Al.sub.2 O.sub.3, 0-5% V.sub.2 O.sub.5, 0-5% TiO.sub.2, 0-5% MoO.sub.3 and 0-5% WO.sub.3. The cements exhibit particular utility in forming strong cellular ceramic articles. The glass powders may contain a phosphate component in which case the composition ranges are limited to 68-76% SiO.sub.2, 18-24% K.sub.2 O, 2-4.5% P.sub.2 O.sub.5 with the molar ratio K.sub.2 O:P.sub.2 O.sub.5 ranging between 5 and 10, and 2-5% total of at least one metal oxide selected from the group of Al.sub.2 O.sub.3, MoO.sub.3, V.sub.2 O.sub.5 and WO.sub.3.

Abstract: An optical fiber of the graded index type consisting of a glass having predominantly the composition 60-70 mole % SiO.sub.2, 15-30 mole % alkali metal oxides, and 10 to 15 mole % MgO in combination with at least one oxide selected from the group formed by CaO, SrO, BaO and ZnO. The impurity content of the fiber is less than 0.01 ppm. In the fiber the MgO content increases from the axis of the fiber to the circumference of the fiber. The oxide or the other oxides, having cations which can be exchanged for the magnesium cation, decrease to a corresponding extent in this direction.

Abstract: The method of the invention provides a thin film deposit of a binary glass for use in integrated circuits which binary glass has a softening or flow point far below temperatures at which glasses normally used in connection with integrated circuits flow. After the binary glass has been deposited (on a semiconductor substrate), it is heated and reflowed. Preferably the glass comprises a mixture of germanium dioxide and silicon dioxide wherein the germanium dioxide is no greater than approximately 50 mole percent of the mixture. Phosphorus is added to the glass film for passivation of the underlying devices.
