Application

Permanent Magnets: One of the most important applications of samarium is the production of samarium cobalt (SmCo) magnets. These permanent magnets are known for their high magnetic strength and excellent thermal stability, making them ideal for use in high-performance applications such as motors, generators, and sensors. SmCo magnets are particularly valuable in the aerospace and defense industries, where reliability and performance are critical.
Nuclear Reactors: Samarium is used as a neutron absorber in nuclear reactors. It is able to capture neutrons, thus helping to control the fission process and maintain the stability of the reactor. Samarium is often incorporated into control rods and other components, which contribute to the safe and efficient operation of nuclear power plants.
Phosphors and Lighting: Samarium compounds are used in phosphors for lighting applications, especially cathode ray tubes (CRTs) and fluorescent lamps. Samarium-doped materials can emit light at specific wavelengths, thereby improving the color quality and efficiency of lighting systems. This application is important for the development of advanced display technologies and energy-efficient lighting solutions.
Alloying agent: Pure samarium is used as an alloying agent in various metal alloys, especially in the production of rare earth magnets and other high-performance materials. The addition of samarium improves the mechanical properties and corrosion resistance of these alloys, making them suitable for use in the electronics, automotive and aerospace industries.
