Abstract

The invention discloses zirconia aluminosilicate glass which is a high-alkali high-alumina glass composition system containing zirconia, is suitable to the manufacture of glass products with high surface hardness and good scratch-resistant property, and has the advantages of being capable of chemical strengthening treatment. The chemical composition (wt percent) of the glass is as follows: 55 to 65 of SiO2, 10 to 20 of Al2O3, 0 to 2 of Li2O, 5 to 15 of Na2O, 0 to 5 of K2O, 1 to 6 of MgO, 0.5 to 4 CaO, 1.5 to 6.0 of ZrO2, 0.35 to 1.0 of SnO2, 0.2 to 1.2 of CeO2 and 0.4 to 1.3 of Sb2O3. The glass material is suitable to screen protecting materials of flat panel display products (such as liquid crystal displays, liquid crystal display-televisions, media machines, touch screens, automated teller machines, cell phones, and personal digital assistants), and can effectively prevent the surface impact and scratch damage of the flat panel display products.
