Abstract:
The properties of the La 2O 3 doped molybdenum powder have been studied. The La 2O 3 nanoparticles on the surface of molybdenum powder can decrease the intensity of loss peak of molybdenum matrix but increase the peak of Mo3d by the reduction of La(NO 3) 3 doped MoO 2 by hydrogen. The surface of molybdenum powder exposed to the atmosphere can be reduced because the surface is mainly covered by La 2O 3 nanoparticles around molybdenum powder, as a result, the capability of antioxidation of molybdenum can be improved.
