Usage:

Samarium Carbonate has specialized uses in glass, phosphors, lasers, and thermoelectric devices. Samarium is added to ceramics and glasses where it increases absorption of infrared light. It is also used as catalyst and chemical reagent. Samarium catalysts assist decomposition of plastics, dechlorination of pollutants. One of the most important applications of Samarium is in Samarium–Cobalt magnets, which have a nominal composition of SmCo5 or Sm2Co17. These magnets are found in small motors, headphones, and high-end magnetic pickups for guitars and related musical instruments.
