Description:

Samarium (Sm) Metal is a rare earth element known for its magnetic, optical, and catalytic properties. With a silvery-white appearance, samarium is used in permanent magnets, nuclear reactors, catalysts, and electronic devices. It plays a crucial role in aerospace, defense, and green energy applications.

Key Features：

Atomic Number: 62
Density: 7.52 g/cm³
Melting Point: 1,072°C (1,962°F)
Oxidation Resistance: Moderately reactive, forming an oxide layer in air
Magnetic Properties: Strong magnetic characteristics when alloyed

Applications:

Samarium-Cobalt (SmCo) Permanent Magnets

SmCo magnets offer high-temperature stability and strong magnetic strength.
Used in aerospace, defense, medical devices, and high-performance motors.
Ideal for harsh environments where neodymium magnets may lose strength.

Nuclear Reactor Control Rods

Samarium has a high neutron absorption capability, making it useful in nuclear reactors.
Used in control rods to regulate nuclear reactions.

Catalysts in Chemical Reactions

Sm-based catalysts enhance hydrocarbon cracking in the petrochemical industry.
Used in alcohol synthesis, hydrogenation, and polymerization.

Laser and Optical Applications

Samarium-doped materials are used in optical lasers and infrared applications.
Applied in high-precision laser technology and scientific research.

Alloy Additive for Specialized Materials

Samarium is used in metal alloys to improve corrosion resistance and high-temperature performance.
Applied in jet engines, aerospace materials, and advanced coatings.
