Samarium metal is silvery white metal crystal, which is available in powder, foil, rod, sheet, granule and sputtering target. It is hard as iron and own good ductility, but poor electric conductivity. Sm metal is relatively stable in dry air, however in moisture air, the surface oxidize and forms oxide layer. Samarium powder is soluble in water, however insoluble in water, which tends to self ignite. Sm metal easily compound with non-metallic element, for example samarium nitride, samarium hydride, samarium boride, samarium sulfide. There are two production methods, reduction method and distillation method. The distilled samarium piece is dendritic with higher purity than reduced one.

Samarium powder apply to make permanent magnets, carbon arc lamp, infrared absorbing glass,neutron absorber of reactor. Calcium oxide crystal doped with Sm can use as laser material. Samarium powder is raw material for production of samarium diiodide and various alloys. It play a part in many organic reactions too.
