Lutetium, is a chemical element with the symbol Lu and atomic number 71. It is a silvery white metal, which resists corrosion in dry, but not in moist air. Unlike most rare earths it lacks a magnetic moment. It also has the smallest metallic radius of any rare earth. It is perhaps the least naturally abundant of the lanthanides.It is the ideal host for x-ray phosphors because it produces the densest known white material, lutetium tantalate (LuTaO4).It is utilized as a dopant in matching lattice parameters of certain substrate garnet crystals, such as indium-gallium-garnet (IGG) crystals due its lack of a magnetic moment.
