一种墨绿色高铝玻璃及其制备方法
摘要：
本发明公开一种墨绿色高铝玻璃，所述玻璃按摩尔百分比包含以下组分：59～69 mol%的SiO2、10～18mol%的Al2O3、8～14 mol%的Na2O、1～3 mol%的K2O、2～8mol%的MgO、0.1～0.4 mol%的CaO、0.1～0.4 mol%的B2O3、0.1～0.4 mol%的SnO2、0.2～0.5mol%的CuO以及0.1～0.3mol%的Cr2O3；制备时按上述的组分配制玻璃配合料，然后对玻璃原料加热熔融得到玻璃液；再对玻璃液进行浇铸成型、退火后得到墨绿色高铝玻璃；区别于目前传统的有色玻璃，本发明玻璃组份中含有较高的二氧化硅与氧化铝，而两者正是提高玻璃强度与硬度的关键成份，本发明在实现墨绿色目的同时，保证了玻璃强度与硬度的提升，且制备工艺简单,易于实现。
摘要（英）：

The invention discloses dark green high-aluminum glass. The glass is prepared from the following components in percentage by mole: 59mol%-69mol% of SiO2, 10mol%-18mol% of Al2O3, 8mol%-14mol% of Na2O,1mol%-3mol% of K2O, 2mol%-8mol% of MgO, 0.1mol%-0.4mol% of CaO, 0.1mol%-0.4mol% of B2O3, 0.1mol%-0.4mol% of SnO2, 0.2mol%-0.5mol% of CuO and 0.1mol%-0.3mol% of Ce2O3. During preparation, glass batch is prepared from the components, then glass raw materials are heated and molten, and molten glass is obtained; the molten glass is subjected to cast molding and annealing, and the dark green high-aluminum glass is obtained. Different from traditional colored glass at present, the glass components contain higher content of SiO2 and Al2O3, which are the key components for improving strength and hardness of the glass. Improvement of strength and hardness of the glass is guaranteed while dark green is realized, and the preparation process is simple and easy to implement.
