Lutetium sputtering target is a metal target made of high-purity Lutetium (Lu) metal. It has a melting point of 1663°C, a boiling point of 3395°C, and a density of 9.84g/cm3.
Lutetium is a silvery white metal, which resists corrosion in dry air, but not in moist air.
The lutetium atom is the smallest among the lanthanide atoms, due to the lanthanide contraction, and as a result lutetium has the highest density, melting point, and hardness of the lanthanides.
