Samarium Metal and Compounds

Samarium, Sm

Atomic No.: 62

M.W.: 150.36 g/mole


One of the most important applications of Samarium is in Samarium–Cobalt permanent magnets, which have a nominal composition of SmCo5 or Sm2Co17.

Samarium in oxidized form has been used as dopant in titanate compounds (BaTiO3-SrTiO3) to optimize dielectric properties suitable for coatings for application of capacitors at microwave frequencies.

Due to its weak spectral absorption band, Samarium is used in the filter glass on Nd:YAG solid state lasers to surround the laser rod to improve efficiency by absorbing stray emissions.

In addition, samarium is added to ceramics and glasses where it increases absorption of infrared light.

Other important application of Samarium include catalyst and chemical reagent.

Samarium oxalate compound has specialized uses in glass, phosphors, lasers, and thermoelectric devices.
