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.
