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.

GHS Hazard and Precautionary Statements

Hazard Statements: H228-H260

Flammable solid. In contact with water releases flammable gases which may ignite spontaneously.

Precautionary Statements: P223-P210-P231+P232-P280a-P240-P241-P370+P378c-P335+P334-P402+P404-P501a

Keep away from any possible contact with water, because of violent reaction and possible flash fire. Keep away from heat/sparks/open flames/hot surfaces. - No smoking. Handle under inert gas. Protect from moisture. Wear protective gloves and eye/face protection. Ground/bond container and receiving equipment. Use explosion-proof electrical/ventilating/lighting/ equipment. In case of fire: Use for extinction: CO2, sand, extinguishing powder. Brush off loose particles from skin. Immerse in cool water/wrap in wet bandages. Store in a dry place. Store in a closed container. Dispose of contents/container in accordance with local/regional/national/international regulations.
