  • Publication number: 20140141226
    Abstract: Ion-exchangeable glasses having high hardness and high elastic modulus. The base cover glass formulation includes Na2O, Y2O3, Al2O3, and SiO2. The glasses may further include P2O5, B2O3, and any of the alkali, alkaline earth, and rare earth oxides, as well as other divalent metal oxides. The ion-exchangeable glasses offer higher hardness, which provides more resistance to micro-ductile scratching damage. Ion-exchange of these glasses increases their resistance to cracking caused by frictive damage and increases retained strength following formation of surface damage.
