摘要：

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　Mo　3d.　The　surface　of　molybdenum　powder　exposed　to　the　atmosphere　is　reduced　because　the　surface　is　mainly　covered　with　La2O3　nanoparticles.　As　a　result,　the　capability　of　anti-oxidation　of　molybdenum　is　improved.
