Samarium Metal

Product Detail

Brief information Formula: Sm CAS No.: 7440-19-9 Molecular Weight: 150.36 Density: 7.353 g/cm³ Melting point: 1072°C Appearance: Silvery lump pieces, ingots, rod, foil, wire, etc. Stability: Moderately reactive in air Ductibility: Good Multilingual: Samarium Metall, Metal De Samarium, Metal Del Samario Application: Samarium Metal is primarily 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 speciality alloy and sputtering targets. Samarium-149 has 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. Specification
