Abstract:
本发明涉及玻璃制造领域，公开了一种玻璃用组合物、化学强化玻璃及其制备方法和应用。该组合物含有42-64wt％的SiO2、15-28wt％的Al2O3、1-15wt％的B2O3+P2O5、4-15wt％的Na2O、0-8wt％的Li2O、0-6wt％的K2O、0.5-9wt％的MgO+TiO2、0.1-4wt％的ZnO、0.1-4wt％的Y2O3+La2O3+Nd2O3，并且该组合物满足如下条件：(1)粘度为100泊对应的温度T100为1700℃以上；(2)1300℃表面张力小于420mN/m。本发明的玻璃用组合物和制备方法制备得到的玻璃具有夹杂物含量低、制备工艺简单、成本低等优点。
Abstract(English):

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.
