摘　　要：本文采用等离子体电弧法制备了纳米Al粉末,用XRD、TEM、TG、DTA、热处理等测试技术研究了纳米Al粉末的组成结构、晶粒大小、晶粒形貌和热稳定性情况。结果表明,该粉体平均粒径是39nm,晶粒形貌为球状,热稳定性好。Al nanopowders were prepared by a arc discharging plasma method. The typical structure, particle size, morphology and thermal stability of the Al nanopowders were investigated by XRD, TEM, heat-treatment,TG and DTA technologies. The results show that the nanopowders of Al are nano-sized with the particle size of 39nm, sphere morphology, material of thermal stability.
