Rare-earth element 62

Samarium

Forms permanent magnets that retain performance at high temperatures and supports specialised nuclear and medical uses.

Rare Earth Matrix

Why it is used

The properties behind samarium applications.

01

High-temperature magnetic stability in Sm-Co systems

02

Strong neutron-absorption behaviour in selected isotopes

Medical references involve produced samarium isotopes administered under specialist regulatory control.

Typical applications

Where samarium is commonly used.

01

Samarium-cobalt magnets

02

Aerospace systems, sensors and precision motors

03

Neutron control and specialised medical isotopes

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.

  1. 01Mineral-bearing material

    Geology and assays establish occurrence and distribution.

  2. 02Recovery and separation

    Testwork must establish what can be mobilised, recovered and purified.

  3. 03Application-grade material

    Oxides, metals, alloys or compounds must meet a controlled specification.

  4. 04Component or system

    Manufacturers design the material into a qualified product.

Sources

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.
