Erbium foil, 0.1mm (0.004in) thick, 99.9% (REO)


Chemical Properties

Soluble in acids. Insoluble in water.


Erbium foil is commonly used as a photographic filter, and because of its resilience it is useful as a metallurgical additive. It is used as an alloying element with titanium and is also used to produce infra-red absorbing glass. Used in nuclear technology for control rods; an alloy in vanadium to lower hardness, lasers and erbium doped fiber amplifiers, a colorant in glass and porcelain.


It is moisture sensitive store under inert gas. Store away from oxidizing agents, acids, water/ moisture.
