摘要： An analytical method for the quantitative determination of the impurities in silicon dioxide by which trace amounts of hardly soluble impurities contained in silicon dioxide can be reliably decomposed and converted into a solution so that the contents of all of the impurities contained in silicon dioxide or, in particular, zirconium in a natural quartz powder can be accurately determined. Silicon dioxide is decomposed with hydrofluoric acid or an acid mixture of hydrofluoric acid and another inorganic acid to give a decomposition solution which is, as such or after admixture with another inorganic acid, subjected to evaporation to dryness and the residue is heated to cause fusion with addition of a salt or hydroxide of an alkali metal followed by dissolution of the salt or hydroxide of an alkali metal with pure water or with an aqueous solution of an inorganic acid to give an aqueous solution which is subjected to quantitative analysis of the impurities therein.

摘要： A light-weight base body of a reflecting mirror, such as those used in reflecting astronomical telescopes, is proposed which is made from fused silica glass or high-silica glass and is advantageous in respect of the excellent thermal and mechanical stability in dimensions to ensure high performance of the reflecting mirror. The base body is composed of a front plate, i.e. a surface plate to provide the optical surface, and a supporting body of porous foamed glass integrally bonded to the front plate. These two parts of the base body can be bonded together by sandwiching a layer of a finely divided silica powder therebetween and heating the assemblage at a temperature higher than the softening point of the silica powder so that the silica powder is softened or melted to firmly join the two parts sandwiching the powder layer. The base body can be further improved in respect of the mechanical stability by providing a rear plate backing the porous foamed body and a reinforcing hoop-like side layer surrounding the side surface of the porous foamed body, each made from fused quartz glass or high-silica glass and bonded to the porous foamed body by utilizing melting of a layer of silica powder therebetween.

摘要： A reactor vessel includes a quartz glass body having sidewalls and a ceiling formed as a single unit without welds. Translucent or opaque portions are formed by bubbles in the glass where heat insulation is desired and transparent portions are formed by absence of bubbles where heat transmission and visibility are desired. The body is formed by adding quartz glass powder to a mold which is rotated about a central axis so that centrifugal force causes a layer of powder to form on the inside of the mold. The layer is then heated until it melts.
