Description

Erbium is a soft, malleable, silvery-white rare earth metal belonging to the lanthanide series. Its unique optical and nuclear properties make it a critical material for advanced technology and research applications. This high-purity element is essential for manufacturers and R&D facilities in the photonics, nuclear, and specialty alloy sectors seeking reliable, high-quality material for precision applications.

Application

• Photonics & Fiber Optics: As a key dopant in optical fibers and amplifiers to boost signal strength in telecommunications networks.
• Medical & Dental Lasers: Used in solid-state laser crystals (e.g., Er:YAG) for precise surgical and dermatological procedures.
• Nuclear Industry: Utilized as a neutron-absorbing material in control rods and as a burnable poison in nuclear reactors.
• Specialty Metallurgy: An alloying additive to improve the workability and strength of vanadium and other non-ferrous metals.
• Glass & Pigment Manufacturing: Imparts a distinctive pink color to glass and is used in ceramic glazes and decorative glassware.
• Upconversion Nanomaterials: Serves as a dopant in nanoparticles for bio-imaging, sensing, and display technologies.
• Research & Development: A fundamental material for academic and industrial research in materials science and chemistry.

Quality Control

Our erbium is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing purity, metallic impurities, and physical characteristics. Our quality systems are designed to meet the stringent requirements of advanced manufacturing and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., argon) in a cool, dry, well-ventilated area. Due to its pyrophoric nature in powder form, appropriate safety measures must be observed. Keep away from strong acids and oxidizing agents.
