摘　　要：以AlCl3 和Li3 N为前驱物 ,利用过量Li3 N与水反应大量放热现象 ,引发两种前驱物之间的固相反应合成了AlN纳米粉 .X射线衍射分析、红外吸收光谱、透射电子显微镜以及X射线光电子能谱测试结果表明 ,利用这种新的合成方法制备的氮化铝主要是六方相 ,而且颗粒细小 .另外 ,这种方法反应迅速、操作过程简便 。AlN nanoparticles were prepared by the water induced solid state reaction method, with AlCl 3 and Li 3N as the starting materials. The results of X-ray diffraction (XRD) analysis, Fourier transformation infrared (FT-IR) absorption spectra measurement, the transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS) observation proved that, the sample we prepared with this method was hexagonal AlN. Besides, the particles were very small. The water induced solid state reaction method includes many merits, such as, the reaction complete in a very short time period, and the experimental process is very simple. It is possible to prepare AlN nanoparticles on a large scale with very low cost by this method.
