  • Metal nitrides as performance modifiers for glass compositions
    Patent number: 6207284
    Abstract: Silicate based glass compositions with nitrogen compounds are included in the composition as performance modifiers to impart desirable color and improved energy absorbance properties. The nitrogen compound is, generally, a metal nitride which is added to the batch glass composition in amounts greater than 0.05 weight percent prior to melting the composition and method resulting in a finished glass suitable for use in architectural and automotive glazings.
    Type: Grant
    Filed: October 20, 1998
    Date of Patent: March 27, 2001
    Assignee: Libben-Owens-Ford Co.
    Inventors: Srikanth Varanasi, Paige L. Higby, Gwendolyn A. Young
  • Method of making glasses containing spectral modifiers
    Patent number: 6196027
    Abstract: The invention is a method of making silicate based glass compositions with phosphorus compounds included in the composition as spectral modifiers to impart desirable color and improved energy absorbance properties. The phosphorus compound is generally a metal phosphide which is added to the batch glass composition in amounts greater than 0.05 weight percent prior to melting. The composition and method result in a finished glass suitable for use in architectural and automotive glazings.
    Type: Grant
    Filed: July 22, 1999
    Date of Patent: March 6, 2001
    Assignee: Libbey-Owens-Ford Co.
    Inventors: Srikanth Varanasi, Michael B. Purvis, Paige L. Higby, Kevin V. Goodwin, Gwendolyn A. Young
  • Metal borides as performance modifiers for glass compositions
    Patent number: 6133176
    Abstract: Silicate based glass compositions with boron compounds are included in the composition as performance modifiers to impart desirable color and improved energy absorbance properties. The boron compound is, generally, a metal boride which is added to the batch glass composition in amounts greater than 0.05 weight percent prior to melting the composition and method resulting in a finished glass suitable for use in architectural and automotive glazings.
    Type: Grant
