Description

This rare earth metal is soft and silver-white with a moderate melting point. Pure samarium exhibits a very rich set of magnetic properties at different temperatures, and its cobalt alloys are used to manufacture high temperature magnets. It has a high thermal-neutron cross section, which means that it is capable of absorbing neutrons efficiently, making it suitable for its use in nuclear reactor control rods. Similar properties also make this metal useful in CRT TV screens and in IR-absorbing glasses.
