Alkali-alumino-silicate glass

A glass contains 47.5% to 55% by weight of SiO2, 21% to 27.5% by weight of Al2O3, 12% to 16% by weight of Na2O, and the molar ratio of Al2O3:Na2O varies from 0.9:1 to 1.2:1. The glass is characterized by high hardness and high surface strength after being chemically hardened, so that it can be used...

More Information
Summary:A glass contains 47.5% to 55% by weight of SiO2, 21% to 27.5% by weight of Al2O3, 12% to 16% by weight of Na2O, and the molar ratio of Al2O3:Na2O varies from 0.9:1 to 1.2:1. The glass is characterized by high hardness and high surface strength after being chemically hardened, so that it can be used as the glass for display devices because of its high abrasion resistance. The glass is also characterized by its viscosity which is lower than the Gorilla glass and Xensation glass.
