Abstract:
High crystalline transparent glass-ceramic has a wide range of applications in solid state laser, infrared generator, infrared detector, infrared domes, nuclear imaging and detecting, high-energy particle detectors ，CT scanner,window masks, lighting and information fields due to its many excellent properties,.such as the inherent characteristics of high temperature resistance, corrosion resistance, high insulation and high strength similar to transparent ceramics.Compared to the crystals with high transmittance, the transparent glass-ceramic has also many advantages including simple process, large size and less influence from impurity. Obviously,high crystalline transparent glass-ceramic is a kind of new generation materials with great significance to national security and sustainable development of national economy and can be expected to replace transparent crystal and transparent ceramic materials which are difficult to prepare by using present technology and equipment.In this paper,some new progress of development in high crystallinity and transparent glass ceramics is briefly introduced,focusing on the research status and trend of Na2O-CaO-SiO2 (NCS), MgO-Al2O3-SiO2 (MAS), TeO2-Bi2O3-ZnO (TBZ), Gd2O3-SiO2 (GSO) and Gd2O3-Ga2O3-GeO2 (GGG) systems.
