Product Overview

W&Q Erbium Oxide (Er₂O₃), also called erbia, is a high-purity rare earth oxide independently developed by W&Q. It presents as pink crystals or rose-pink powder with stable chemical properties, insoluble in water but soluble in mineral acids, and excellent thermal stability (melting point 2344°C, boiling point 3290°C). With strict production standards and advanced purification technologies, W&Q ensures its erbium oxide has a purity range of 99.5% to 99.999%, widely applied in optical communication, laser technology, nuclear industry and new materials for global high-end manufacturing.

2. Laser Technology Field

W&Q Erbium Oxide is key to Er:YAG lasers, used in precise medical surgeries (reducing tissue damage) and industrial cutting/welding of hard materials, improving efficiency and precision.

3. Nuclear Industry Field

With excellent neutron absorption capacity, W&Q Erbium Oxide is made into "burnable neutron poison" for nuclear reactor control. It has passed IAEA and US NRC certifications, trusted by 27 global nuclear power plants.

4. New Materials & Other Fields

W&Q Erbium Oxide is a colorant/modifier for high-end ceramics, and its nanoparticles are used in functional coatings, biomedical imaging and solar cells. It also enhances special alloys for aerospace and precision instruments.

FAQ

Q1: What is the purity range of W&Q Erbium Oxide, and how to verify it?

A1: W&Q offers 99.9% (industrial), 99.99% (optical) and 99.999% (nuclear) grades. Purity is verified by SR-XRD analysis, with a formal COA provided for each batch.

Q2: What is the difference between nuclear-grade and fiber-grade W&Q Erbium Oxide?
