摘要：

Magnetic ultrafine particles Fe3O4 and Fe C, prepared by means of the electric are plasma technique for different atmospheric pressures of argon (Ar), were studied by wide-angle X-ray diffraction, transmission electron microscopy, and X-ray photoelectron spectrometer. Argon atmospheric pressure dependence of the ultrafine particles size, microstructure and compositions were found, and the mechanism was explored preliminarily.
