Being bismuth trioxide glass and the process null bismuth trioxide

摘要

Topic Disclose the appropriate process which produces the glass, and the glass which include the bismuth trioxide where the prerequisite which responds to application field is improved.SolutionsThis invention includes the additive of bismuth oxide and germanium oxide, B₂ O content of₃ and SiO₂ 0.1 mols % is more, at the same time 5 mols % regards the glass which is under. As for this invention, in addition, it regards the method of being suited for the production of the aforementioned glass. As for the glass of this invention when doping the especially rare earth, it can use optical activity as the glass.
