The aluminum powder is a high energetic material. It is added into energetic materials. The results show that the critical conditions of shock ignition for micrometer-aluminum powder relate with physical behaviour for aluminum powder. The micro-behaviour of the fast reaction for micrometer-aluminum powder are studied by means of some spectrometer techniques-three monochromaters techniques and OMA spectral techniques. The critical temperature for the micrometer-aluminum powder is about 2 100 K, and it is closed to the melting temperature of Al2O3. It is show that the Al2O3 layer must be melted, if the micrometer-aluminum powder may be ignited. It is important that the reaction of micrometer-aluminum powder with oxygen. It is not important that the reaction of micrometer-aluminum powder with water. The micrometer-aluminum powder may react, after a liquid fuel in compound fuel reacts. The reaction temperature is increased when micrometer-aluminum powder is added into energetic material and the particle size of micrometer-aluminum powder is decreased.
