Preparation of Nanometric Particles of Aluminum Nitride by Pyrolysis of Diethylaluminun Azide

Thermal stabilities of diethylaluminum azide were studied by means of theoretical analysis and expriments.The results have shown that diethylaluminum and azid be heated to vigorous refluxing under vacuum(400 Pa) at temperature as high as 420℃ without incident of explosion and decomposes smoothly during 460~580℃ to form nanometric particles of aluminum nitride in the aerosol synthesis reactor. A new way of preparing nanometric parties of aluminum nitrideis found.
