ALKALI-FREE GLASS AND METHOD FOR MANUFACTURING SAME

摘要

Disclosed are a structure for alkali-free glass which does not comprise alkali metal oxides, and a method for manufacturing such glass. The alkali-free glass according to the present invention contains 46-57% SiO2, 3.5-7.5% B2O3, 21-29% Al2O3, 3-14% MgO, 11-16% CaO, and 1-5% SrO, in terms of weight % of oxides, and does not substantially contain alkali metal oxides.
