초록

A glass composition is disclosed which has a high modulus of elasticity (Young's modulus) and a high rigidity (modulus of elasticity/specific gravity) and is capable of being effectively inhibited from bending or vibrating. Also disclosed is process for producing the glass composition. The glass composition comprises, in terms of mol %, 40 to 65% SiO2, 5 to 25% Al2O3, 2 to 20% Li2O, 0 to 9% Na2O, 0 to 10% TiO2, 0 to 10% ZrO2, 0 to 25% MgO, 0 to 25% CaO, and 0 to 10% SrO, provided that the content of RO (RO=MgO+CaO+SrO) is from 2 to 40% and the sum of (Li...
