High-Purity Nano Samarium Oxide (Sm₂O₃) 99.999% | Magnets Supplier

Nano Samarium Oxide (Sm₂O₃) 99.9% – High Purity, Engineered for Performance

Our nano samarium oxide is a high-purity (99.9%) rare earth powder designed for demanding industrial and high-tech applications. With a pale yellow appearance, high melting point (2335°C), and a well-defined cubic crystal structure, this material delivers consistent performance in critical environments. It remains paramagnetic at room temperature, is insoluble in water, and readily soluble in acids—ideal for advanced manufacturing processes.

Why Choose Our Nano Samarium Oxide?

• Superior Purity & Stability
  ≥99.9% trace metal basis, with controlled particle size (80–150 nm) and BET surface area (6.83 m²/g). Sealed packaging ensures protection from moisture and CO₂, preserving product integrity.

• High Neutron Absorption
  Contains Sm-149 isotope with an exceptionally high thermal neutron capture cross-section—making it a trusted material for nuclear reactor control rods, neutron absorbers, and shielding components.

• Critical for High-End Magnets
  A key raw material for samarium-cobalt (SmCo) permanent magnets, offering outstanding magnetic performance, temperature stability, and corrosion resistance—essential for aerospace, defense, and high-performance motors.

• Versatile in Catalysis & Electronics
  Functions as a highly active catalyst in petroleum refining (e.g., ethanol dehydration, methane reforming) and automotive exhaust treatment. In electronics, it enhances dielectric properties in MLCCs and piezoelectric ceramics.

• Precision in Phosphors
  The Sm³⁺ ion provides characteristic orange-red emission, making it suitable for X-ray intensifying screens and specialized displays.
