Goodfellow offers samarium pellets as part of their range of pellets. Samarium is a rare earth metal with a bright silver luster. It has a high thermal neutron absorption cross-section and is therefore used in control rods for nuclear reactors. Samarium pellets also have strong magnetic properties and are used in permanent magnets and microwave filters. The high purity samarium pellets from Goodfellow provide researchers and engineers with a versatile material for nuclear, electronic and magnetic applications.
