  • Glass with anionic conductivity for fluorine
    Patent number: 4649126
    Abstract: The invention relates to halide-containing glass. Glass with anionic conductivity for fluorine comprises PbO, F, and a glass-forming agent. As the glass-forming agent boron oxide (B.sub.2 O.sub.3) is used, with the following proportions of the components, per cent by mass:PbO: 86.0 to 87.0F: 3.5 to 0.5B.sub.2 O.sub.3 : 10.5 to 12.5Glass with anionic conductivity for fluorine is intended, mainly, for making dividers of electric signals.
