Sodium Sticks are a form of metallic sodium supplied by Goodfellow as part of their range of sodium products. The sodium pellets have a lustrous, silvery appearance and are soft enough to be cut with a knife. Their low melting point of 97.8°C and high reactivity make sodium useful for chemical synthesis and as a heat transfer fluid. Sodium pellets can also be used to produce sodium vapour lamps and as a reactant in sodium-cooled fast neutron nuclear reactors. With minimal oxidation and high purity, Goodfellow's sodium sticks provide an effective source of elemental sodium for research and industrial applications.
