| 简介 |
本文揭示的为不透明玻璃-陶瓷，该等不透明玻璃-陶瓷包含至少一个霞石晶相且包含约30mol%至约65mol% SiO2、约15mol%至约40mol% Al2O3、约10mol%至约20mol%(Na2O+K2O)，以及约1mol%至约10mol%(ZnO+MgO)。本文亦揭示的为不透明玻璃陶瓷，该等不透明玻璃陶瓷包含至少一个霞石晶相及至少一个尖晶石结构相，该至少一个尖晶石结构相掺杂有选自过渡金属及稀土元素之至少一种着色剂。本文进一步揭示的用於制造此等不透明玻璃-陶瓷之方法。 Disclosed herein are opaque glass-ceramics comprising at least one nepheline crystal phase and comprising from about 30 mol% to about 65 mol% SiO2, from about 15 mol% to about 40 mol% Al2O3, from about 10 mol% to about 20 mol% (Na2O+K2O), and from about 1 mol% to about 10 mol% (ZnO+MgO). Also disclosed herein are opaque-glass ceramics comprising at least one nepheline crystal phase and at least one spinel-structure phase doped with at least one colorant chosen from transition metals and rare earth elements. Further disclosed herein are methods for making these opaque glass-ceramics. |
