American Elements specializes in producing high purity Thulium Circles with the highest possible densityand smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. Our standard Circle sizes range from 1" to 8" in diameter and from 2mm to 1/2" thick. We can also provide Circles outside this range. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also 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 (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We also produce Thulium as rod, pellets, powder, pieces, granules, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.
Thulium is a Block F, Group 3, Period 6 element. The number of electrons in each of Thulium's shells is 2, 8, 18, 31, 8, 2 and its electronic configuration is [Xe]4f136s2. In its elemental form thulium's CAS number is 7440-30-4. The thulium atom has a radius of 172.4.pm and it's Van der Waals radius is unknown. Thulium is not toxic. Thulium is representative of the other lanthanides (rare earths) similar in chemistry to Yttrium. Thulium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Thulium emits blue upon excitation. Flat panel screens depend critically on bright blue emitters. Also, under X-ray bombardment emissions are in both the 375 nm (ultra violet) and 465 (visible blue) wave lengths. This gives the material useful applications in low radiation detection for detection badges and similar uses. It is also used in other luminescence applications, such as halide discharge lamps. Thulium was first discovered by Theodore Cleve in 1879. Thulium is named after "Thule", which is the ancient name of Scandinavia. See Thulium research below.
PACKAGING SPECIFICATIONS FOR BULK & RESEARCH QUANTITIES
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. Shipping documentation includes a Certificate of Analysis and Material Safety Data Sheet (MSDS). Bullion and bar forms are best if purchasing solely for physical possession and risk exposure.
