Abstract: The properties of La2O3-doped molybdenum powder were studied. The La2O3 nanoparticles on the surface of molybdenum powder which is produced by the reduction of La(NO3)3-doped MoO2 in hydrogen decrease the intensity of feature energy loss peak of molybdenum substrate; but increase that of peak of Mo3d. The surface of molybdenum powder exposed to the atmosphere can be reduced because the surface is mainly covered with La2O3 nanoparticles. As a result, the capability of anti-oxidation of molybdenum is improved.
