于耐火金属熔融坩埚中制备石英玻璃体
摘要：
本发明涉及一种制备石英玻璃体的方法，其包含方法步骤i.)提供二氧化硅颗粒，ii.)在熔融坩埚中自所述二氧化硅颗粒制造玻璃熔体，和iii.)从至少一部分所述玻璃熔体制造石英玻璃体，其中所述熔融坩埚包含在烘箱中且由包含钨或钼或其组合的至少一种材料制成。本发明进一步涉及一种可通过此方法获得的石英玻璃体。此外，本发明涉及一种光导、一种照明体和一种成型体，其中每一者可通过进一步加工所述石英玻璃体获得。
摘要（英）：

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, and iii.) forming a silica glass article from at least some of the glass melt, the melting crucible being contained in a furnace and being made of at least one material containing tungsten, molybdenum or a combination thereof. 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.
