目的：制备硼酸铝晶须及测其物理化学特征。方法：原料在电炉中加热至１１５０℃，４ｈ，获得的晶须采用化学方法确定其组成，物理化学方法检测其表征。结果：获得了晶须的化学组成、Ｘ射线粉末衍射图、ＦＴ－ＩＲ光谱和Ｒａｍａｎ光谱图。结论：制备的晶须为四硼酸十八铝。
OBJECTIVE: To prepare aluminum borate whiskers and measure their physico-chemical characteristics. Methods: Raw materials were heated to 1150 ℃ in an electric furnace for 4h. The obtained whiskers were chemically identified by their chemical composition, and the physical and chemical properties of the obtained whiskers were tested. Results: The whisker chemical composition, X-ray powder diffraction pattern, FT-IR spectrum and Raman spectrum were obtained. Conclusion: The prepared whiskers are octadecyl aluminum tetraborate.
