Abstract The crystal habit, crystalline structure, surface condition and composition ofthe ultrafine Al particles, prepared by an inert gas evaporation method, were studied in detailby means of high resolution transmission electron microscope, X-ray diffraction and X-rayphoto-electron spectrum. The particles are of clear crystal habits, single crystal in a large ma-jority and fcc crystalline structure with α_0=0.405 nm. A protective layer of amorphousAl_2O_3, 2 nm in average thickness, against oxidizing further was found around the particles. Itis believed that the ultrafine Al particles prepared by the inert gas evaporation method arevery stable in atmosphere.
