Lutetium is a chemical element with the symbol Lu and atomic number 71. It is a silvery white metal, which resists corrosion in dry air, but not in moist air. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths.

Phase at STP: solid

Melting point: 1925 K (1652 °C, 3006 °F)

Boiling point: 3675 K (3402 °C, 6156 °F)

Density (near r.t.): 9.841 g/cm3

when liquid (at m.p.): 9.3 g/cm3

Heat of fusion ca.: 22 kJ/mol

Heat of vaporization: 414 kJ/mol

Molar heat capacity: 26.86 J/(mol·K)


Lutetium usually occurs in association with the element yttrium and is sometimes used in metal alloys and as a catalyst in various chemical reactions. 177Lu-DOTA-TATE is used for radionuclide therapy (see Nuclear medicine) on neuroendocrine tumours.
