Process Flow Diagram


Erbium Oxide is a highly insoluble thermally stable Erbium source suitable for glass, optical, and ceramic applications. Erbium oxide is a solid compound of erbium and is pink in color. Erbium oxide can be also used as a flammable neutron poison for nuclear fuel. 

Erbium Oxide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. 

Erbium has applications in glass coloring, as an amplifier in fiber optics,and in lasers for medical and dental use. Rare Earth oxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. 

They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity.

 Erbium oxide is also available in pellets, pieces, powder, sputtering targets, tablets, and nanopowder.



In sealed double polyethylene bags. The bags are packed in steel drums containing 25 or 50 Kgs net each.


Specification is adjustable as per user' s special requirement.
