Description
Overview
Terbium is a silvery-white rare earth metal that is soft and ductile. It is typically processed into ingots, powder, or as terbium oxide for industrial use. Known for its green phosphorescence and ability to enhance magnetic properties, terbium is a key material in phosphors, magnets, and electronics. It is primarily extracted from monazite and bastnäsite ores.
Properties
- Composition: Typically 99.9% or higher pure terbium.
- Density: 8.23 g/cm³.
- Melting Point: 1,356°C (2,473°F).
- Color: Silvery-white, metallic, and shiny (tarnishes in air).
- Malleability: Moderately malleable, can be shaped with processing.
- Ductility: Limited ductility, can be drawn into wires with effort.
- Electrical Conductivity: Poor conductor, resistivity ~115 μΩ·cm at 20°C.
- Thermal Conductivity: Low, ~11.1 W/(m·K) at 20°C.
- Corrosion Resistance: Reactive, oxidizes in air, forms oxide layer; reacts with acids.
Applications
- Phosphors for fluorescent lamps and LED lighting
- Magnetostrictive alloys (e.g., Terfenol-D for sensors, actuators)
- High-performance magnets (e.g., in wind turbines)
- Flat-panel displays and TVs (e.g., green phosphors)
- Solid-state devices (e.g., lasers, amplifiers)
Packaging options
Standard Format:
Terbium ingots or powder, typically 1–5 kg per ingot
Packaging:
Options for secure, moisture-proof packaging
Custom Sizes Available:
Can be processed into specific forms (e.g., powder, foil)
Market outlook
Terbium’s demand is driven by its use in energy-efficient lighting and magnetostrictive alloys. Terbium oxide prices are around $600–$800 per kg as of early 2025, influenced by China’s dominance in rare earth production. The market is expected to grow with demand for green technologies, though prices may fluctuate due to supply constraints and export policies.
