Samarium is a metal element with a chemical symbol of Sm and an atomic number of 62. This is a medium-hard silver-white metal that is easily oxidized in the air. As a typical part of the lanthanide series, samarium is usually assumed to have an oxidation state of +3. The most common compounds of samarium(II) are SmO, SmS, SmSe and SmTe. Samarium has no significant biological effects, only slight toxicity

Application field
It is used in the manufacture of laser materials, microwave and infrared equipment, and also has more important uses in the atomic energy industry.
Used in the electronics and ceramic industries. Samarium is easy to magnetize but difficult to demagnetize, which means that there will be important applications in solid-state components and superconducting technology in the future.
