Erbium Oxide (Er_O3) is a rare earth oxide prized for its unique optical and electronic properties. Erbium(III) oxide, is synthesized from the lanthanide metal erbium. (Er_O3) was first obtained in pure form in 1905. Characterized by its distinctive pink color (cubic crystal structure), dierbium trioxide is a chemically stable material with a high melting point, making it suitable for high-performance applications in Photonics and advanced ceramics, & with it's unique optical properties, making it indispensable for the global expansion of 5G infrastructure and high-speed data networks. Also known as oxo(oxoerbiooxy)erbium by rare earth manufacturers. We are one of the leading metallurgy chemical Supplier worldwide, ensuring comprehensive regulatory support & CoA traceability for various electronic & specialty grades with global supply capability with reliable lead time.

Chemical Properties & Specifications
H319 (12.7%): Serious eye damage/eye irritation
H400 (37.3%): Hazardous to the aquatic environment, acute hazard
H410 (37.3%): Hazardous to the aquatic environment, long-term hazard
Dopant in Erbium-Doped Fiber Amplifiers (EDFAs) for telecommunications
Provides a pink tint to glass and is used in nuclear control rods as a burnable neutron poison
Essential in the synthesis of phosphors for biomedical imaging and anti-counterfeiting
Store in a dry area at ambient temperature
Keep in original moisture-proof packaging. Rare earth oxides can slowly absorb moisture and CO2 from the atmosphere if left exposed
Non-flammable, but standard protective gloves and safety glasses are recommended to prevent mechanical irritation from the powder on storage
It has a unique optical transition at 1550 nm, which is the standard wavelength for long-distance telecommunications
The pink color is an inherent property of the Erst ion and is utilized specifically in the coloring of glass and ceramic glazes.
It was noticed in 2025, the Industrial-grade Erbium Oxide (99%–99.9%) is priced between ₹950/kg to ₹5,000/kg depending on quantity. High-purity reagent grades (≥99.99%) for laboratory use can reach ₹1,08,200 to ₹1,20,000 per kg.
Asia-Pacific continues to dominate production (over 60% of output). Europe drive demand for ultra-high purity grades used in defense and aerospace technologies.
Generally, the HS Code is 28469090 for Rare Earth Oxides (Standard code for Erbium Oxide in many regions)
Yes. High-k dielectric Erbium Oxide for semiconductors.
