Product Code : RE-Tb-5N-DI
Terbium is a silvery-white rare earth metal that is malleable, ductile and soft enough to be cut with a knife. It is reasonably stable in air, and two crystal allotropes exist, with a transformation temperature of 1289 °C. Terbium(III) cation is brilliantly fluorescent, in a beautiful bright lemon-yellow color that is the result of a strong green emission line in combination with other lines in the orange and red. The yttrofluorite variety of the mineral fluorite owes its creamy-yellow fluorescence in part to terbium.
Terbium (Tb) Sheet/Foil/Disc is made of the rare earth metal Terbium, which can be used in scientific research or industrial production.
ATT specializes in producing Terbium as rolled discs in various thicknesses and sizes. 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 Terbium as rods, powder and plates. Other shapes are available by request.

Applications of Terbium (Tb) Metal
Terbium Metal Tb is applied in petroleum and environment protection catalysts, mischmetal, polishing powders and Rare Earth fertilizers.
Terbium is used to dope calcium fluoride, calcium tungstate and strontium molybdate, all used in solid-state devices. It is also used in low-energy lightbulbs and mercury lamps. It has been used to improve the safety of medical x-rays by allowing the same quality image to be produced with a much shorter exposure time. Terbium salts are used in laser devices.
An alloy of terbium, dysprosium and iron lengthens and shortens in a magnetic field. This effect forms the basis of loudspeakers that sit on a flat surface, such as a window pane, which then acts as the speaker.
Packing of Terbium (Tb) Disc
Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.
ATTs’Terbium (Tb) Disc is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
