Abstract：
 Preparation of a single crystal AlN nano chain of new methods, which includes the following specific steps: (1) Al powder as raw materials, the introduction of 2 to 11 wt% nitric acid containing iron or iron nitrate crystal water as a catalyst; (2) mixtures After mixed evenly placed in the crucible; (3) will be placed crucible furnace atmosphere, all-or nitrogen and ammonia nitrogen gas mixture (4) in 1100 -1450 degree C reaction temperature range, for 2 to 8 hours; (5) With the furnace cooling to room temperature. Compared with the existing technology, the advantages of this invention lies in the preparation of nano-crystal AlN chain structure perfect, low cost, simple technology and equipment, and high-yield, high purity. This unique structure of low dimensional nanostructures used as a nano-device is expected to harsh working conditions in high-temperature environments such as light and thermal conductivity materials, as well as high-pressure environment of field emission source material.
