| Abstract: | Ferrous ultrafine powders have been obtained via laser plasma induced dissociation ofFe(CO)_5 using TEA-CO_2 pulsed laser.The electron diffraction pattern of the powders shows that it con-sists of pure polycrystalline Fe. TEM photograph of the powders reveals that their particle sizes are about140 and have good qu.ality. The special chemical reaction mechanism of IR laser plasma induced dis-sociation of Fe(CO)_5 is also discussed. |
