一种琉璃绀色高铝玻璃及其制备方法
摘要：
本发明公开一种琉璃绀色高铝玻璃，所述玻璃按摩尔百分比包括以下组分：59～69 mol%的SiO2、10～18mol%的Al2O3、8～14mol%的Na2O、1～3 mol%的K2O、2～8mol%的MgO、0.1～0.4 mol%的CaO、0.1～0.6mol%B2O3、0.1～0.7 mol%的SnO2、0.01～0.06mol%的MnO2以及0.005～0.04mol%的Co2O3；制备时，按照上述的组分配制玻璃配合料；然后熔制玻璃配合料得到熔融的玻璃液；接着将玻璃液经过浇铸成型、退火步骤后，得到所述琉璃绀色高铝玻璃；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，本发明在实现琉璃绀色目的同时，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 glass violet blue high alumina glass. The glass is prepared from the following components in molar percentage: 59 to 69 mol% of SiO2, 10 to 18 mol% of Al2O3, 8 to 14 mol% of Na2O, 1 to 3 mol% of K2O, 2 to 8 mol% of MgO, 0.1 to 0.4 mol% of CaO, 0.1 to 0.6 mol% of B2O3, 0.1 to 0.7 mol% of SnO2, 0.01 to 0. 06 mol% of MnO2 and 0.005 to 0.04 mol% of Co2O3. During preparation, aglass batch is prepared according to the above components; then the glass batch is molten to obtain molten glass liquid; then the glass liquid is subjected to the steps such as casting and annealing to obtain the glass violet blue high alumina glass. Different from traditional colored glass, the components of the glass disclosed by the invention contain higher silica and alumina, and the both arekey components to improve the strength and hardness of the glass; while the purpose of realizing the violet blue color of the glass is realized, the strength and hardness improvement of the glass is ensured, and the preparation technology is simple, and easy to implement.
