    Abstract: This invention relates to the discovery of a method for incorporating various oxides into silica-containing porous and nonporous glass materials by dissolving soluble compounds of the additive oxides, characterized as MxOy, into solutions, colloidal solutions, or suspensions of soluble silicates, reacting the mixture with an organic compound, and then firing the thus-formed body at temperatures below the softening point of the particular glass composition for a sufficient length of time to produce the porous body or non-porous glass body containing the added oxides intimately bonded to the silica network.

    Abstract: This invention provides a method for manufacturing an optical glass in order to prevent the deterioration of the burner used in the synthesis of glass particles that form the optical glass, and to obtain a stable quality optical glass. In this invention, the number of residual bubbles with a diameter of 0.3 mm and more is 0.005/cm3 or less per unit volume of the optical glass. Such optical glass is obtained by controlling the temperature of an end face of the burner for glass synthesis during the deposition of the glass particles by regulating the relationship of the flow velocity or the flow volume between an inflammable gas and a combustion-supporting gas.

    Abstract: In a known process for the production of opaque quartz glass a blank is formed from synthetic SiO2 granulate and is heated at a vitrification temperature to form a body of opaque quartz glass. In order to provide on this basis a process for the production of pure opaque quartz glass with a homogenous pore distribution, high density, high viscosity and a low tendency to devitrify, it is proposed according to the invention that the SiO2 granulate to be used is a SiO2 granulate (21; 31) composed of at least partially porous agglomerates of SiO2 primary particles, with a specific BET surface ranging from 1.5 m2/g to 40 m2/g and an apparent density of at least 0.8 g/cm3. A SiO2 granulate (21; 31) suitable for the implementation of the process is distinguished in that it is formed from at least partially porous agglomerates of SiO2 primary particles and in that it has a specific BET surface ranging from 1.5 m2/g to 40 m2/g and an apparent density of at least 0.6 g/cm3.
