Erbium

Amplifies the light signals that carry data through long-distance fibre-optic networks.

Rare Earth Matrix

Why it is used

The properties behind erbium applications.

Efficient optical amplification near telecommunications wavelengths

Useful laser emission and glass coloration

Typical applications

Where erbium is commonly used.

Fibre-optic signal amplifiers

Medical and industrial lasers

Specialised glass and ceramics

Applications refer to suitable rare-earth materials, compounds or produced isotopes—not raw mineral material. Product designs and formulations vary.

Route to use

A head assay is several steps from an industrial material.

01Mineral-bearing material
Geology and assays establish occurrence and distribution.
02Recovery and separation
Testwork must establish what can be mobilised, recovered and purified.
03Application-grade material
Oxides, metals, alloys or compounds must meet a controlled specification.
04Component or system
Manufacturers design the material into a qualified product.

Where the element and application information comes from.

Applications are representative rather than exhaustive. They describe industry uses of rare-earth materials, compounds or produced isotopes; they do not describe a product currently made by Magnes or establish that an element will be commercially recovered from Minas Americas.
