Oxide IonYttrium Oxide is a highly insoluble thermally stable Yttrium source suitable for glass, optic and ceramic applications. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Metal oxide compounds High Purity (99.999%) Yttrium Oxide (Y2O3) Powderare basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. Metallic oxide compounds are also available from American Elements' nanoscale production facilities. See Nanotechnology for more nanotechnology applications information. Yttrium Oxide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale () elemental powders and suspensions, as alternative highsurface area forms, may be considered. Yttrium has the highest thermo-dynamic affinity for oxygen, useful in ceramics for crucibles for molten reactive metals, in florescent phosphors, computer displays and automotive fuel sensors. Yttria stabilized zirconia is used in high temperature applications and as an electrolyte in fuel cells. Yttrium Oxide oxide is also available in pellets, pieces, sputtering targets, tablets, and nanopowder (from American Elements' nanoscale production facilities). Additional technical, research and safety (MSDS) information is available.

Yttrium Bohr ModelYttrium (Y) atomic and molecular weight, atomic number and elemental symbolYttrium (atomic symbol: Y, atomic number: 39) is a Block D, Group 3, Period 5 element with an atomic weight of 88.90585. The number of electrons in each of yttrium's shells is [2, 8, 18, 9, 2] and its electron configuration is [Kr] 4d1 5s2. The yttrium atom has a radius of 180 pm and a Van der Waals radius of 219 pm. Yttrium was discovered by Johann Gadolin in 1794 and first isolated by Carl Gustav Mosander in 1840. Elemental Yttrium In its elemental form, Yttrium has a silvery white metallic appearance. Yttrium has the highest thermodynamic affinity for oxygen of any element. Yttrium is not found in nature as a free element and is almost always found combined with the lanthanides in rare earth minerals. 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. The name yttrium originated from a Swedish village near Vaxholm called Yttbery where it was discovered.
