摘要
Phosphorus-aluminum silicate glass with a high compressive stress layer, comprising: 65-75% of SiO2, 8-16% of Al2O3, 11-18% of Na2O, 0-5% of K2O, 1-4% of P2O5, 0-3% of B2O3, 0-1% of ZnO, and 0-0.4% of SnO2, wherein, (CaO+MgO+SrO+BaO) is less than or equal to 0.1%; the depth of the ion exchange layer of the reinforced glass is greater than or equal to 60μm; and the mean line thermal expansion coefficient of the glass is less than 90×10-7/°C. After soaking for 6 hours in an oxalic acid solution at 60°C, the weight loss rate of the unit area is less than or equal to 0.15 mg/cm3.
