Abstract
A composition for glass, and aluminosilicate glass, preparation method therefor, and use thereof. In molar percentage, in the composition, the total content of SiO2, B2O3, P2O5, GeO2 and TeO2 is 60˜85 mol %; the total content of Al2O3 and Ga2O3 is 3˜20 mol %; the total content of ZnO and Y2O3 is 0.1˜5 mol %; and the total content of alkaline earth metal oxide is 4˜30 mol %. The glass has a high strain point, a low melting temperature, and a high thermal expansion coefficient, has good toughness, and is suitable for large-scale industrial production.
