FLOAT GLASS FOR DISPLAY SUBSTRATE AND PROCESS FOR PRODUCING THE SAME

WIPO Patent Application WO/2007/129744

A1

A float glass for display substrate that without losing of the performance as a substrate glass for display, attains lowering of high-temperature viscosity. There is provided a float glass for display substrate characterized by having a composition composed substantially of, by mass% on an oxide basis, 52 to 62% SiO2, 5 to 15% Al2O3, over 0 to 9% MgO, 3 to 12% CaO, 9 to 18% SrO, 0 to 13% BaO, 25 to 30% MgO+CaO+SrO+BaO, 6 to 14% Na2O+K2O+Li2O, 0 to 6% ZrO2 and 0 to 1% SO3, and characterized in that the temperature of glass melt corresponding to a viscosity of 102 dPas is 1520°C or below, the temperature of glass melt corresponding to a viscosity of 104 dPas is 1120°C or below, the glass transition temperature is 610°C or above and the specific gravity is 2.9 or below.
