Samarium Chloride has specialized uses in glass, phosphors, lasers, and thermoelectric devices.
Samarium Chloride is used for the preparation of Samarium metal, which has a variety of uses, notably in magnets.
Anhydrous SmCl3 is mixed with Sodium Chloride or Calcium Chloride to give a low melting point eutectic mixture.
Electrolysis of this molten salt solution gives the free metal.
Samarium Chloride can also be used as a starting point for the preparation of other Samarium salts.
