Erbium powder is made from erbium metal ingot, including erbium metal by reduction method and distillation method, which is a kind of soft gray rare earth metals. Its reaction with air and water is very slow, which is not soluble in water, but solbule in acids. At high temperature Erbium metal could react with halogen, oxygen, nitrogen, carbon, silicon, hydrogen and sulfur to form erbium iodide (ErI3) , erbium oxide (Er2O3), erbium nitride (ErN), erbium carbide (ErC2), erbium silicide (ErSi2), erbium hydride (ErH2) and erbium sulfide (Er2S3). Erbium metal is raw material for various erbium alloys too. Aluminum-erbium alloy is common. Other erbium alloys are available too, such as aluminium-magnesium-erbium alloys, aluminium-lithium-erbium alloys, aluminium-copper-erbium alloys, zirconium-erbium alloys and so on.

Erbium metal get uses in nuclear and alloys for example vanadium-erbium alloys, titanium-erbium alloys. Till now, the most prominent application is erbium dopant fiber amplifier. It is doping small amount of erbium ion in quartz fiber. Another prospect application is laser , especially medical laser. Erbium is laser ion that transferring laser materials including monocrystal(fluoride, oxysalt) and fiberglass, for example Er:YAP crystal and ZrF4-BaF2-LaF3-AlF3-NaF fiberglass. These already get commercial uses. Yb,Er:BaYF5 can convert infrared ray to visible light. This kind of photo converting material apply to night-vision successfully.
