摘要：

Aluminum nitride nanofibers are synthesized by the direct reaction of aluminum fluoride with sodium azide. The reaction product (grayish white powder) is investigated using a scanning electron micro-scope. The results testify that the product has fibrous morphology with a fiber diameter reaching 100 nm. The effect of the pressure of external nitrogen in a reactor, the relative density of the starting charge, and the sample diameter on the temperature and rate of combustion of the AlF3-3NaN(3) system is shown. Optimum production conditions of the synthesis of aluminum nitride nanofibers are determined.
