  • Process for melting and refining silica-based glass
    Patent number: 8806896
    Abstract: A process for making silica-based glass includes: (a) forming a glass precursor melt that includes glass network formers and glass network modifiers, the glass precursor melt having a viscosity of not more than 30 Pa·s at 1300 C., and (b) refining the glass precursor melt. Either or both steps (a) and (b) can include stirring and/or be carried out under reduced pressure to enhance refining. The refined glass precursor melt preferably is mixed with additional materials including silica (SiO2) to form a silica-based glass melt.
    Type: Grant
