69TmHeavy rare earth
Rare-earth element 69
Thulium
A scarce element used in specialised lasers, compact radiation sources and scientific systems.
Rare Earth MatrixWhy it is used
The properties behind thulium applications.
Radiation from selected produced isotopes
Radiation-source and medical references may involve produced thulium isotopes under specialist regulatory control.
Typical applications
Where thulium is commonly used.
Solid-state lasers
Specialised portable X-ray sources
Scientific instrumentation and materials research
Applications refer to suitable rare-earth materials, compounds or produced isotopes—not raw mineral material. Product designs and formulations vary.
Connected technologies
What the element does inside a system.
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.
