摘要：
A carburized La2O3 and Lu2O3 co-doped Mo filament cathode is made from lanthanum oxide (La2O3) and lutetium oxide (Lu2O3) doped molybdenum (Mo) powders, the lanthanum oxide (La2O3) and lutetium oxide (Lu2O3) doped molybdenum (Mo) powders contain La2O3, Lu2O3 and Mo with the total concentration of La2O3 and Lu2O3 being 2.0-5.0 wt. % and the rest being Mo.
