【摘要】：泡生法作为众多蓝宝石晶体生长方法的一种,因相比于其他方法生长出的晶体具有重量大、质量高的优势而被广泛地采用。但在实际生产中,利用泡生法制备蓝宝石的工艺还存在着很多问题,比如利用泡生法生长出晶体时常会出现气泡,晶界,甚至开裂等缺陷,蓝宝石晶体的合格率并不理想,这都是因为原有制备工艺还不够完善,需要很多改进的地方,比如原料的处理方法、热场的设计、引晶工艺的设计都是影响生产出来的蓝宝石质量好坏的关键。本课题改进了原有的泡生法工艺,制备出了质量更高、性能更好的蓝宝石晶体,并且通过X射线衍射仪,红外光谱仪,激光显微拉曼光谱仪等表征了样品的各项性能。与此同时系统地研究了各类晶体缺陷的形成机理,并提出了相应的解决措施。
[Abstract]:As one of the many growth methods of sapphire crystals, bubble growth method is widely used because of its advantages of large weight and high quality compared with other methods. There are still many problems in the process of preparing sapphire by bubbling method. For example, bubbles, grain boundaries and even cracks often appear in crystal growth by bubbling method. The qualified rate of sapphire crystals is not ideal. This is because the original preparation process is not perfect enough, and many improvements are needed, such as the treatment of raw materials, the design of the thermal field, The design of crystal inductive process is the key to the quality of sapphire produced. In this paper, we have improved the original bubbling process, prepared sapphire crystal with higher quality and better performance, and made it by X-ray diffractometer. The properties of the samples were characterized by infrared spectrometer and laser micro-Raman spectrometer. At the same time, the formation mechanism of various crystal defects was systematically studied, and the corresponding solutions were put forward.
