Abstract
The present invention relates to the field of glass manufacturing, and discloses aluminoborosilicate glass, and a preparation method and an application thereof. Based on the total weight of components in the composition of the glass, the glass comprises: 33-60 wt % SiO2, 3-10 wt % Al2O3, 10-30 wt % B2O3, 1-15 wt % ZnO+TiO2+Sc2O3, and 7-27 wt % alkaline-earth oxide RO, wherein RO is at least one of MgO, CaO, SrO and BaO, and 0.001 wt %≤Sc2O3≤1 wt%. The aluminoborosilicate glass provided in the present invention has advantages including low density, high index of refraction, low thermal expansion coefficient, high thermostability, high flexibility, and easy bending, etc.
