The vaporized iron pentacarbonyl (Fe(CO)5) carried by argon gas is pyrolyzed in the oxygen plasma generated by a microwave plasma jet. Fe2O3 powder with an average particle size of 26 nm is synthesized, which is identified and characterized by energy dispersive X-ray analysis (EDX), X-ray diffraction (XRD), and scanning electron microscopy (SEM). It is shown that operating the microwave plasma jet in the continuous flow mode at atmosphere is promising for the mass production of nanosized metal oxide powders other than nanocrystalline iron oxide particles, economically and efficiently 关键词: iron compounds;materials preparation;nanoparticles;nanotechnology;particle size;plasma materials processing;powder technology;pyrolysis;scanning electron microscopy;X-ray chemical analysis;X-ray diffraction;nanocrystalline iron oxide particles;microwave plasma jet;atmospheric pressure;gas phase synthesis;vaporized iron pentacarbonyl compound;argon gas;pyrolysis;oxygen plasma generation;Fe2O3 powder;particle size;energy dispersive X-ray analysis;EDX;X-ray diffraction;scanning electron microscopy;SEM;mass powder production;continuous flow mode;nanosized metal oxide powders;XRD;26 nm;Fe2O3
