  • Nitride glasses and methods of making same
    Patent number: 5518970
    Abstract: The present invention relates generally to a novel and unique class of gly materials and methods of making such materials in which substantially all of the anions are nitride ions, in contrast to the oxide ions of conventional optical glasses, or the fluoride ions of the more recently discovered fluoride optical glasses. The chemical nature of these new glasses dispose the glassy materials to a remarkable combination of desirable properties, including, but not limited to, high hardness, high refractive index and high softening temperature.
    Type: Grant
    Filed: May 24, 1995
    Date of Patent: May 21, 1996
    Assignee: Arizona Board of Regents acting on behalf of Arizona State University
