  • Creep resistant zircon refractory material used in a glass manufacturing system
    Publication number: 20050130830
    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 %).
