  • Creep resistant zircon refractory material used in a glass manufacturing system
    Patent number: 7238635
    Abstract: A glass manufacturing system is described herein that has a forming device (e.g., isopipe) which is made from a zircon refractory material that has an improved creep resistance property. The zircon refractory material has a composition with at least the following elements: ZrSiO4 (98.75–99.68 wt %); ZrO2 (0.01–0.15 wt %); TiO2 (0.23–0.50 wt %); and Fe2O3 (0.08–0.60 wt %).
    Type: Grant
    Filed: December 16, 2003
    Date of Patent: July 3, 2007
    Assignee: Corning Incorporated
