Abstract
The invention provides a composition for glass, a glass, and a preparation method and application thereof. On an oxide basis, the composition for glass contains 45-64 wt % SiO, 16-26 wt % AlO, 0.1-2 wt % MgO, 10-17 wt % NaO, 0.5-15 wt % PO, and optionally 0-2 wt % TiO. The glass prepared from the composition for glass has a higher chemical resistance, a higher strain point, and a higher compressive stress and depth of compressive stress layer formed on the glass surface, and the glass has a higher Young's modulus.
