Product Code : RE-Tm-5N-SP
Thulium metal is a bright, lustrous, soft, malleable, silvery rare earth metal, a member of the periodic table's lanthanide group. It is the second least abundant of the lanthanides only after promethium. It can be cut with a knife. Thulium Metal is mainly used in making superalloys. It has some application in ferrites (ceramic magnetic materials) used in microwave equipment and as a radiation source of portable X-ray. Thulium potentially has usage in ferrites, ceramic magnetic materials that are used in microwave equipment. It is used in arc lighting for its unique spectrum.
The melting point is 1545°C, the boiling point is 1947°C, and the density is 9.3208. Thulium is relatively stable in the air. The atomic number of thulium is 69 and the atomic weight is 168.93421.
ATT specializes in producing Thulium as rolled sheets in various thicknesses and sizes. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. ATT casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes and through other processes such as nanoparticles and in the form of solutions and organometallics. We also produce Thulium as rods, powder and plates. Other shapes are available by request.

Features
The silver-gray metal of the rare earths is very soft, easily stretchable and malleable.
In dry air, thulium is quite stable, in moist air it turns gray. At higher temperatures it burns to Sesquioxid.With water, it reacts with evolution of hydrogen to the hydroxide. In mineral acids, it dissolves to form hydrogen.
In its compounds it is present in the oxidation state + 3, the Tm3 + cations form pastel-bluish-green solutions in water.
Thulium (Tm) Sheet Application
170Tm outsourced from nuclear reactors serves as X-ray source (gamma emitter in materials testing)
Thulium-doped yttrium tantalate or lanthanum oxybromide (LaOBr) serves as a scintillator in X-ray intensifying screens or X-ray screens
Thulium-doped calcium sulfate serves as a detector in personal dosimeters for the measurement of low radiation doses
Thulium crystals can be used as the active medium in diode-pumped solid-state lasers (wavelength 2 μm) with an overall efficiency of up to 10% at maximum 60 W light output.
Thulium-doped silica glass as an active medium in fiber lasers (wavelength 2 µm) was operated with a differential efficiency of 53,2% at a power> 1000 W.
Thulium and thulium compounds are low in toxicity. Thulium dusts are fire and explosive.
Packing of Thulium (Tm) Sheet
Standard Packing:
