Description:

Praseodymium (Pr) is a soft, silvery, malleable rare-earth metal belonging to the lanthanide series. It slowly oxidizes in air, forming a green oxide layer.

CAS No.: 7440-10-0
Atomic Number: 59
Atomic Weight: 140.91 g/mol
Density: 6.77 g/cm³
Melting Point: 931°C (1,708°F)
Boiling Point: 3,520°C (6,368°F)
Magnetic Properties: Paramagnetic at room temperature

Key Properties:

High corrosion resistance (when stored properly)
Strong absorption of neutrons (useful in nuclear applications)
Forms colorful compounds (green oxides, yellow salts)
Excellent alloying properties (enhances strength & workability)

Applications:

Magnets & Alloys

Used in high-strength permanent magnets (e.g., Pr-Nd-Fe-B alloys for motors, wind turbines, and headphones).
Improves heat resistance in NdFeB magnets.

Glass & Optics

Decolorizer and colorant for specialized glasses (produces yellow-green hues).
Used in welder’s goggles (absorbs infrared radiation).
Key component in fiber optic amplifiers.

Catalysts & Chemical Processes

Used in automotive catalytic converters (reduces emissions).
Acts as a cracking catalyst in petroleum refining.

Ceramics & Pigments

Praseodymium yellow (Pr-ZrSiO₄) – A stable, bright yellow pigment for ceramics and paints.
Used in glazes and artistic glassware.

Nuclear Applications

Neutron absorber in control rods for nuclear reactors.
Used in radiation shielding research.

Electronics & Superconductors

Used in high-temperature superconductors.
Found in laser materials (e.g., Pr:YLF lasers).
