American Elements specializes in producing high purity irregular shaped Thulium Oxide Pieces with the highest possible density 99.999% Ultra High Purity Oxide Pieces

99.999% Ultra High Purity Oxide Pieces

and smallest possible average grain sizes for use in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Our standard Pieces sizes average in the range of 3 mm, 4 -5 mm, 100 - 150 mm, 1/8" and 1/4". We can also provide Pieces outside this range. We also produce Thulium as pellets, tablets,powder, and sputtering target. Oxide compounds are not conductive to electricity. See research below. Other shapes are available by request.

Thulium is a Block F, Group 3, Period 6 element. The 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 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.
