氧化铝、氢氧化铝的XRD鉴定

Appraisal of alumina and aluminium hydroxide by XRD

氧化铝、氢氧化铝的晶型有多种,不同晶型的氧化铝、氢氧化铝的用途差别也很大,所以必须确定它们的晶型。X射线衍射仪在区别物质晶型方面有独特的优势。在参考前人工作的基础上,介绍了不同晶型的氧化铝、氢氧化铝的X射线衍射图及其特征衍射峰,并分析了衍射峰之间的差别,以及鉴定方法。并简单介绍了不同晶型的氧化铝、氢氧化铝的用途。

Alumina and aluminium hydroxide have many crystal types. The uses are quite different between different crystal types of alumina and aluminium hydroxide. Therefore, it is very necessary to identify their crystal types. XRD has its unique advantages in the field of appraising matter＇s crystal type. Based on the predecessor＇s work, X - ray diffraction patterns and characteristic diffraction peaks of alumina and aluminium hydroxide with different crystal types were introduced. The difference and appraising method of diffraction peaks were analyzed. In addition, the uses of alumina and aluminium hydroxide with different crystal types were briefly introduced.
