摘要:
An ion exchangeable glass that is free of lithium and comprising 0.1-10 mol % P2O5 and at least 5 mol % Al2O3. The presence of P2O5 enables the glass to be ion exchanged more quickly and to a greater depth than comparable glasses that do not contain P2O5.

A silicate glass that is tough and scratch resistant. The toughness is increased by minimizing the number of non-bridging oxygen atoms in the glass. In one embodiment, the silicate glass is an aluminoborosilicate glass in which −15 mol %≦(R2O+R′O—Al2O3—ZrO2)—B2O3≦4 mol %, where R is one of Li, Na, K, Rb, and Cs, and R′ is one of Mg, Ca, Sr, and Ba.
