Thulium Acetate is a moderately water soluble crystalline Thulium source that decomposes to Thulium oxide on heating. It is generally immediately available in most volumes. Acetates are excellent precursors for production of ultra high purity compounds and certain catalyst and nanoscale(nanoparticles and nanopowders) materials. All metallic acetates are inorganic salts of a metal cation and the acetate anion. The acetate anion is a univalent (-1 charge) polyatomic ion composed of two carbon atoms ionically bound to three hydrogen and two oxygen atoms (Symbol: CH3COO) for a total formula weight of 59.05. High purity, submicron and nanopowder forms may be considered. Thulium emits blue upon excitation in flat panel screens and under X-ray bombardment emits both the 375 nm (ultra violet) and 465 (visible blue) wave lengths giving it useful applications in low radiation detection for detection badges and similar uses. We also produce Thulium Acetate Solution.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
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.
Acetate is an anion used as a ligand in metal complexes. The formula is CH3CO2-, C2H3O2-, or CH3COO-. Metal acetates are used in biology, printing, vinyl acetate in plastic production, volatile organic esters as solvents and cellulose acetate in photographic films and textiles. Cellulose acetate, one of the first synthetic fibers, is often called acetate.
