American Elements specializes in producing high purity Yttrium discs with the highest possible density and smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. Our standard disc sizes range from 1" to 8" in diameter and from 2mm to 1/2" thick. We can also provide Discs 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.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. See safety data and research below and pricing/lead time above. We also produce Yttrium as as rod, pellets, powder, pieces, granules, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.
Yttrium is a Block D, Group 3, Period 5 element. The number of electrons in each of Yttrium's shells is 2, 8, 18, 9, 2 and its electronic configuration is [Kr] 4d1 5s2. In its elemental form Yttrium's CAS number is 7440-65-5. The yttrium atom has a radius of 177.6.pm and it's Van der Waals radius is 200.pm. Insoluble compounds of Yttrium are non-toxic, although water soluble compounds are somewhat toxic. Yttrium has the highest thermo-dynamic affinity for oxygen of any element. This characteristic is the basis for many of its applications. While not part of the rare earth series, it resembles the heavy rare earths which are sometimes referred to as the “yttrics” for this reason. Another unique characteristic derives from its ability to form crystals with useful properties. Yttrium 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 assubmicron and nanopowder. Some of the many applications of yttrium include in ceramics for crucibles for molten reactive metals, in florescent lighting phosphors, computer displays and automotive fuel consumption sensors.Yttria stabilized zirconium oxide are used in high temperature applications, such as in thermal plasma sprays to protect aerospace high temperature surfaces and as an electrolyte in solid oxide fuel cells. The name Yttrium originated from a Swedish village near Vaxholm called Yttbery where Yttrium was discovered. Crystals of the yttrium-iron-garnet (YIG) variety are essential to microwave communication equipment. The phosphor Eu:Y2O2S creates the red color in televisions. Crystals of the yttrium-aluminum-garnet (YAG) variety are utilized with neodymium in a number of laser applications. Yttria can also increase the strength of metallic alloys. Yttrium was first discovered by Johann Gadolin in 1794. See Yttrium research below.
