Chemical Properties

≈0.14g/25x25mm, Packaged under argon
Insoluble in water.


Erbium foil used in Physical Vapor Deposition (PVD) processes, including thermal and electron-beam (e-beam) evaporation, for the preparation of thin films. It is used as an alloying element with titanium and is also used to produce infra-red absorbing glass.


Hygroscopic. Incompatible with oxidizing agents and acids.
