Abstract
The present invention discloses an aluminosilicate glass composition, aluminosilicate glass and a preparation method therefor and application thereof. Based on the total molar weight of the aluminosilicate glass composition, the aluminosilicate glass composition comprises, by oxide, 67-74 mol % of SiO2, 10-15 mol % of Al2O3, 0-5 mol % of B2O3, 1-10 mol % of MgO, 1-10 mol % of CaO, 0-3 mol % of SrO, 2-8 mol % of BaO, 0.1-4 mol % of ZnO, 0.1-4 mol % of RE2O3 and less than 0.05 mol % of R2O, wherein RE represents rare earth elements, and R represents alkali metals.
