Uses
Samarium(III) chloride (CAS NO.10361-82-7) 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 lower the melting point, then it is melted and electrolysed to give the free metal. The anhydrous chloride may also be used to prepare organometallic compounds of samarium, such as bis(pentamethylcyclopentadienyl)alkylsamarium(III) complexes used as catalysts for hydrogenation and hydrosilylation of alkenes. Samarium(III) chloride can also be used as a starting point for the preparation of other samarium salts.

Specification
Samarium trichloride is a compound of samarium and chlorine. It is a pale yellow solid which rapidly absorbs water on exposure to moist air to form a hexahydrate, SmCl3.6H2O. Simple rapid heating of the hydrate alone may cause small amounts of hydrolysis. The first five moles of water are lost at 110 °C
