Glass for chemical strengthening and glass housing

Abstract

To provide glass for chemical strengthening from which glass having high strength and having excellent solarization resistance is obtained, and a housing such glass. Glass for chemical strengthening comprises, as represented by mole percentage based on oxides, at least from 55 to 80% of SiO2, from 5 to 20% of Na2O, from 0.001 to 3% of Fe2O3 and from 0.001 to 3% of TiO2 and further contains as a coloring component from 0.001 to 10% of MpOq (wherein M is at least one member selected from Co, Cu, V, Cr, Pr, Ce, Bi, Eu, Mn, Er, Ni, Nd, W, Rb, Sn and Ag, and p and q represent the atomic ratio of M and O). A glass housing comprises chemically strengthened glass obtained by subjecting the glass for chemical strengthening to chemical strengthening treatment.
