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 ,有利于降低制备成本和扩大制备规模 Using AlCl3 and Li3N as precursors, AlN nanopowders were synthesized by the reaction of exothermic Li3N with water and induced solid-state reaction between the two precursors.X-ray diffraction analysis, infrared absorption spectroscopy, transmission electron microscopy And X-ray photoelectron spectroscopy test results show that the use of this new synthesis of aluminum nitride prepared mainly hexagonal phase, and small particles.In addition, the method of rapid reaction, the operation is simple, is conducive to reducing the cost of preparation and expansion Preparation scale
