PURPOSE:To develop the titled glass which can be produced in large quantities without requiring the coating for preventing elution of alkali and without the deterioration of performance due to the elution of alkali by using the aluminosilicate glass as the starting material to manufacture the glass which is used as the substrate glass for electronic parts. CONSTITUTION:The glass is manufactured by melting as substrate glass having 0.3-1.0mm thickness which is used for a liquid crystal apparatus. The glass contains 50-62% SiO2, 10-18% Al2O3, 2-5% B2O3, 0.5-7% MgO, 4-13% CaO, 0-7% BaO, 3-10% ZnO, 0-2% LiO2, 0-10% Na2O, and 0-10% K where Li2O+Na2O+K2O=3-11%. The glass is charged into a mold made of stainless steel, and then annealed. The glass which has no deterioration in performance due to the elution of alkali and can be used as the substrate glass for members of electronic and electric products such as a liquid crystal substrate can be obtained.
