一种玻璃用组合物、低表面张力无碱玻璃及其制备方法和应用
摘要：
本发明涉及玻璃制造领域，公开了一种玻璃用组合物，该玻璃用组合物含有SiO2、Al2O3、ZnO、WO3、CaF2和/或SrCl2、碱土金属氧化物和稀土金属氧化物，以玻璃用组合物各组分的总摩尔数为基准，SiO2的含量为68?73.5mol％，Al2O3的含量为11?16mol％，ZnO的含量为0.1?4mol％，WO3的含量为0.001?0.5mol％，CaF2和/或SrCl2的含量为0.3?1.5mol％，碱土金属氧化物的含量为3?20mol％，稀土金属氧化物的含量为0.1?3mol％。还公开了低表面张力无碱玻璃及其制备方法和应用。本发明制得的无碱玻璃的综合稳定性较优异，且表面张力较低。
摘要（英）：

The invention relates to the field of glass manufacturing, and discloses a composition for glass. The composition for glass comprises the following components on the basis of the total mole amount of the components of the composition for glass: 68-73.5mol% of SiO2, 11-16mol% of Al2O3, 0.1-4mol% of ZnO, 0.001-0.5mol% of WO3, 0.3-1.5mol% of CaF2 and/or SrCl2, 3-20mol% of alkaline earth metal oxides and 0.1-3mol% of rare earth oxides. The invention further discloses low-surface-tension alkali-free glass as well as a preparation method and application thereof. The low-surface-tension alkali-free glass disclosed by the invention is relatively excellent in comprehensive stability and relatively low in surface tension.
