Application
Samarium Metal has primarily been utilized in the production of Samarium-Cobalt (Sm2Co17) permanent magnets with one of the highest resistances to demagnetization known. High purity Samarium Metal is also used in making specialty alloy and sputtering targets. Samarium-149 has a high cross-section for neutron capture (41,000 barns) and is therefore used in the control rods of nuclear reactors. Samarium Metal can be further processed to various shapes of sheets, wires, foils, slabs, rods, discs, and powder.
