properties and microstructure of molybdenum powder, sintering product and fabricated wires were studied. The molybdenum powder was produced firstly by reduction of molybdenum oxide which is doped with K2SiO3 and Al(NO3)3?9H2O. Then doped molybdenum powder was cold pressed into cylindrical compact with diameter of 17 mm, and sintered in induction furnace. The microstructure of molybdenum ingots......Effect of dopant content on microstructure and properties ofSi-Al-K doped molybdenum
