Lutetium Foil

Lutetium Foil is a metallic foil made from the rare earth element lutetium, available in thicknesses from 25 to 200 microns, with a purity level of 99.9%. Lutetium has a silvery-white appearance and is relatively soft and malleable. With 16 variations to choose from, our range of Lutetium Foils caters to diverse applications including research and development of new high-temperature superconductors, scintillators for medical imaging and targets for positron emission tomography (PET). Lutetium Foil’s high density and high thermal neutron capture cross section also make it suitable for use as a neutron absorber in nuclear reactor control rods.
