Erbium Oxide (Er2O3): Powering Modern Industries & Innovations

Erbium Oxide (Er₂O₃), a rare earth oxide with the CAS number 12061-16-4, is a critical material driving advancements in optics, nuclear technology, and electronics.

As a leading supplier authorized by China Rare Earth Group, Ruisen delivers high-purity Er2O3 tailored for industrial, research, and commercial applications.

Key Properties & Specifications of Erbium Oxide (Er₂O₃)

Certificate of Analysis

Er₂O₃ is a pink powder with a hexagonal or cubic crystal structure, known for its high dielectric constant and large band gap. Below are its core specifications:

Property Specification
Chemical Formula Er₂O₃
Purity 99.9% (3N), 99.99% (4N)
Particle Size 50 nm – 5 µm (customizable)
Density 8.64 g/cm³
Solubility Insoluble in waterreadily reacts with acids
Stability Stable at high temperatures; resists moisture and carbon dioxide

This compound exhibits exceptional photoluminescence property, making it ideal for fiber optics and laser systems. Its nanoscale form, erbium oxide nanoparticles, is surface-modified for enhanced distribution into aqueous and non-aqueous media, crucial for biomedical applications.

Er₂O₃ vs. Alternatives: Comparative Advantages

Er₂O₃ outperforms substitutes like Y₂O₃ or Al₂O₃ in niche applications. Here’s a competitive comparison:

Feature Er₂O₃ Alternatives
Thermal Stability Stable up to 2,300°C Y₂O₃: 2,400°C
Neutron Absorption High (neutron poison for nuclear fuel) Low in most oxides
Optical Efficiency Superior erbium ions emission Limited in non-lanthanide materials
Cost-Effectiveness Optimal for specialized uses Lower upfront cost

Er₂O₃’s unique chemical and electrical properties solidify its role in semiconductor doping and gate dielectrics.
