Like many other rare earths, this element is used in the production of permanent magnets. Magnets with an alloy of samarium and cobalt are characterized by a high temperature resistance of up to 300 degrees and are therefore ideal for generators and drying ovens, among other things. Another area of application is as an absorber material for thermal neutrons in nuclear technology. It is used in chemical catalysis and cancer therapy. It is also used in optical glass and in laser technology.
