Abstract: Disclosed in the present application is a lithium-aluminosilicate glass. The lithium-aluminosilicate glass includes, by mole percent of oxides, the following components: SiO2, 62-68 mol %; Al2O3, 9-14 mol %; Na2O, 6-10 mol %; K2O, 0.2-0.7 mol %; and Li2O, 8.0-14.0 mol %; where (Li2O+Na2O+MgO)/Al2O3 is 1.7-2.5. By means of controlling the mole percents of SiO2, Al2O3, Na2O, K2O, and Li2O, as well as the range of the ratio (Li2O+Na2O+MgO)/Al2O3, it is consequently ensured that the obtained lithium-aluminosilicate glass, upon chemical strengthening, has high strength, satisfies a requirement of a client with respect to “film-peeling electrostatic voltage”, and further has uniquely advantageous effects of a lower melting temperature and being able to save energy and reduce energy consumption.
