Description
Overview
Erbium is a silvery-white rare earth metal that is relatively stable in air. It is typically processed into ingots, powder, or as erbium oxide. Known for its ability to emit and absorb light in the infrared spectrum, erbium is a critical material in telecommunications and laser technology. It is primarily extracted from monazite and xenotime ores.
Properties
- Composition: Typically 99.9% or higher pure erbium.
- Density: 9.07 g/cm³.
- Melting Point: 1,529°C (2,784°F).
- Color: Silvery-white, metallic, and lustrous (tarnishes slowly in air).
- Malleability: Moderately malleable, can be shaped with effort.
- Ductility: Limited ductility, can be drawn into wires with difficulty.
- Electrical Conductivity: Poor conductor, resistivity ~86 μΩ·cm at 20°C.
- Thermal Conductivity: Low, ~14.5 W/(m·K) at 20°C.
- Corrosion Resistance: Moderately reactive, forms oxide layer in air; reacts with acids.
Applications
- Fiber optic amplifiers (e.g., erbium-doped fiber amplifiers for telecommunications)
- Lasers (e.g., medical and dental lasers)
- Glass and ceramics (e.g., pink coloring agent)
- Nuclear technology (e.g., neutron-absorbing control rods)
- Metallurgy (e.g., to improve grain structure in alloys)
Packaging options
Standard Format:
Erbium ingots or powder, typically 1–5 kg per ingot
Packaging:
Packed in vacuum-sealed or argon-filled containers
Custom Sizes Available:
Can be processed into specific forms (e.g., powder, foil)
Market outlook
Erbium’s demand is driven by telecommunications, particularly fiber optic networks. Erbium oxide prices are around $50–$100 per kg as of early 2025, with China dominating supply. Growth in 5G and internet infrastructure is expected to sustain demand, though the market remains sensitive to rare earth supply dynamics.
