Abstract (en)
[origin: WO2017103133A1] The invention relates to a method for producing a silica glass article, involving method steps i.) providing a silica granulate, ii.) forming a glass melt from the silica granulate in a melting crucible, iii.) forming a silica glass article from at least some of the glass melt, iv.) treating the silica glass article using at least one measure selected from the group consisting of a chemical, a thermal or a mechanical treatment so as to obtain a treated silica glass article. The invention further relates to a silica glass article that can be obtained by said method. The invention also relates to an optical waveguide, an illuminant and a molded article, each of which can be obtained by further processing the silica glass article.
