Erbium Oxide

Erbium(III) Oxide, is synthesized from the lanthanide metal erbium. Erbium oxide is a light pink powder in appearance. It is insoluble in water, but soluble in mineral acids. Er2O3 is hygroscopic and will readily absorb moisture and CO2 from the atmosphere. It is a highly insoluble thermally stable Erbium source suitable for glass, optical, and ceramic applications. Erbium Oxide can be also used as a flammable neutron poison for nuclear fuel.

Ytterbium(III) Oxide is a highly insoluble thermally stable Ytterbium source, which is a chemical compound with the formula Yb2O3. It is one of the more commonly encountered compounds of ytterbium. It is usually used for glass, optic and ceramic applications.
