采用同步辐射白光形貌术对山东蓝宝石的位错等晶体缺陷进行分析研究。山东蓝宝石薄片的同步辐射白光形貌图像揭示,大部分蓝宝石不同程度的存在结构缺陷,其中,样品的不同区域、不同方位、不同颜色的缺陷明显程度不同,特别值得关注的是黄褐色蓝宝石及蓝宝石中黄褐色区域结构缺陷明显,变形严重。其规律性有待进一步研究。 Synchrotron radiation white topography was used to analyze the dislocation and other crystal defects in Shandong sapphire. The synchrotron radiation white topography image of Shandong sapphire flake reveals that most sapphires have structural defects in varying degrees. Among them, the defects of different regions, different orientations and different colors of the samples are obviously different in degree. Of particular note are the yellow-brown sapphires and sapphires In the yellow-brown area, the structural defects are obvious and the deformation is serious. Its regularity needs further study.
