Samarium Metal Sm CAS 7440-19-9 For SmCo Permanent Magnet Material

The metal Samarium, chemical symbol Sm, is a rare earth element that is widely used in many fields due to its unique physical and chemical properties. Samarium is a silver-white metal of medium hardness, easily oxidized in air, but soluble in acid and insoluble in water.
In materials science, samarium is often used to make high-performance permanent magnet materials, such as samarium iron-boron magnets, which play an important role in fields such as electric motors, generators and electric vehicle motors. In addition, samarium is also used in nuclear reactor control, and its isotopes such as samarium-149 and samarium-153 are used as neutron absorbers and radiopharma components, respectively, and have important applications in nuclear energy and medicine.
In the field of optics, samarium can be used to prepare fluorescent materials and optical glasses to improve the performance of lighting and display technologies. At the same time, compounds of samarium also act as catalysts in a variety of chemical reactions, such as hydrogen production and petroleum refining.

Name: Samarium metal

Molecular formula: Sm

CAS: 7440-19-9

Molecular weight: 150.36

Description

Samarium can be made into various forms: Samarium foil, Samarium block and Samarium powder. Samarium is a silver gray metal with medium hardness, which is easy to oxidize in air. Samarium coexists with other rare earth elements in monazite sand, and also exists in bastnaesite. Samarium is stable in dry air, and oxide film is formed on the surface of Samarium in humid air. Metal Samarium can be prepared by reduction-distillation method using metal lanthanum to reduce Samarium oxide, because Samarium has a high vapor pressure and the vapor pressure of the reducing agent lanthanum is low. The metal Samarium produced in the reaction can be removed from the reactor by volatilization, which can promote the reaction to complete.
