Formula: Gd
Form: Foil/Film/Sheet
Material: Gadolinium
CAS Number: 7440-54-2
Commodity: Metals
Purity:
99%
Temper:
As Rolled
Gadolinium (Gd) foil is widely used in neutron capture applications due to its exceptionally high neutron absorption cross-section, making it essential in neutron radiography and in specialized radiation shielding for particle detectors and certain test reactor systems. Its strong paramagnetic properties support advanced magnet design in material science research. Additionally, gadolinium foil is employed in select radiation therapy equipment to help manage exposure in clinical settings. Ongoing studies explore the use of gadolinium foil and thin films for improved shielding efficiency, cryogenic technologies, thin-film sensor development, and high-performance magnetic applications in electronics and aerospace.
