Overview
Erbium (III) Oxide (Er2O3) is a rare-earth compound derived from erbium, a lanthanide series element. It is primarily valued for its optical properties, including its ability to absorb infrared light and emit pink hues in glass matrices. The material is chemically stable and finds specialized roles in high-tech industries. As a heavy rare-earth oxide, it is less abundant than lighter counterparts like cerium oxide. Global production is limited to a few suppliers, predominantly in China, the U.S., and Europe. Its pricing reflects both extraction complexity and niche demand in advanced applications.
Physical and Chemical Properties
Er2O3 exhibits a cubic crystal structure at room temperature, transitioning to monoclinic under high pressure. Its high melting point (2,344°C) and density (8.64 g/cm³) make it suitable for high-temperature environments, such as nuclear reactor components. The compound is insoluble in water but dissolves in mineral acids like hydrochloric acid, forming erbium salts. Its infrared absorption bands at 1.5-1.6 μm are exploited in fiber-optic amplifiers. Notably, it is paramagnetic and exhibits low electrical conductivity.
Main Applications
In optics, Er2O3 is vapor-deposited as an anti-reflective coating for lenses and laser components. Its ability to filter specific wavelengths enhances performance in medical and military laser systems. The glass industry uses it as a pink coloring agent for decorative glassware and UV-protective eyewear. In nuclear technology, it serves as a neutron-absorbing material in control rods due to erbium's high neutron capture cross-section. Emerging applications include dopant materials in perovskite solar cells and quantum dot synthesis.
Safety and Storage
While erbium oxide is non-radioactive and considered low-toxicity, its fine powder form requires handling with dust masks (NIOSH N95 or equivalent) to prevent respiratory irritation. Spills should be cleaned with wet methods to minimize airborne particles. Storage mandates airtight containers with desiccants to prevent moisture absorption, which can affect sintering performance. Incompatible with strong oxidizing agents. No special disposal regulations apply, but landfill disposal should follow local guidelines for heavy metal oxides.
B2B Procurement Guide
Industrial buyers should prioritize purity (≥99.9% for optical grades) and particle size distribution (typically 1-10 μm for coatings). Certificates of Analysis (CoA) should confirm trace metal content, especially for semiconductor applications. Bulk purchases (25+ kg) often qualify for 10-15% discounts. Lead times vary from 2-8 weeks depending on purification requirements. Consider dual sourcing due to geopolitical sensitivities around rare-earth supply chains. Spot prices fluctuate with China's export quotas.
