Abstract

Disclosed are a composition for alkali-free glass which contains no alkali metal oxides, and a method for manufacturing said glass. By weight % on the basis of oxides, the alkali-free glass according to the present invention contains: 61 to 73% of SiO2; 0.5 to 3.9% of B2O3; 3.5 to 13.5% of Al2O3; 9 to 13% of MgO; 1 to 8% of CaO; and 4 to 10% of SrO, and contains substantially no alkali metal oxides.
