摘要（英）：

The invention relates to the field of glass production, and discloses a composition for glass, chemical tempered glass as well as a preparation method and application thereof. The composition is prepared from 42 to 64 weight percent of SiO2, 15 to 28 weight percent of Al2O3, 1 to 15 weight percent of B2O3 and P2O5, 4 to 15 weight percent of Na2O, 0 to 8 weight percent of Li2O, 0 to 6 weight percent of K2O, 0.5 to 9 weight percent of MgO and TiO2, 0.1 to 4 weight percent of ZnO, 0.1 to 4 weight percent of Y2O3, La2O3 and Nd2O3. The composition satisfies the following conditions: (1) the temperature T100 corresponding to the viscosity of 100 is 1700 DEG C or higher; and (2) the surface tension at 1300 DEG C is smaller than 420N/m. The composition for the glass of the invention and glass prepared by the preparation method of the invention have the advantages of low content of impurities, simple preparation process, low cost and the like.
