Abstract: The effect of La2O3 on the microstructure and property of sintered molybdenum has been investigated.It was shown that the sintering density of molybdenum increased,the grain structure was fined obviously and the bending strength and ductility of molybdenum were improved greatly with the addition of La2O3.Moreover,its linear expansion coefficient of sintered molybdenum decreased as well.
