  2. Yttrium(III) oxide - Wikipedia

    en.wikipedia.org/wiki/Yttrium(III)_oxide

    Yttrium oxide is used to stabilize the Zirconia in late-generation porcelain-free metal-free dental ceramics. This is a very hard ceramic used as a strong base material in some full ceramic restorations. [9] The zirconia used in dentistry is zirconium oxide which has been stabilized with the addition of yttrium oxide. The full name of zirconia ...

  3. Yttrium - Wikipedia

    en.wikipedia.org/wiki/Yttrium

    The oxalate is converted into the oxide by heating under oxygen. By reacting the resulting yttrium oxide with hydrogen fluoride, yttrium fluoride is obtained. [66] When quaternary ammonium salts are used as extractants, most yttrium will remain in the aqueous phase.

  4. Yttrium compounds - Wikipedia

    en.wikipedia.org/wiki/Yttrium_compounds

    The oxides and hydroxides of yttrium are yttrium oxide (Y 2 O 3) and yttrium hydroxide (Y(OH) 3), respectively, and they are both white solids which are hardly soluble in water. Among them, yttrium oxide can be prepared by heating yttrium carbonate or yttrium oxalate. Alternatively the oxychloride, Y 3 O 4 Cl can be heated in air to yield the ...

  5. Yttria-stabilized zirconia - Wikipedia

    en.wikipedia.org/wiki/Yttria-stabilized_zirconia

    Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" (Zr O 2) and "yttria" (Y 2 O 3), hence the name.

  6. Rare-earth element - Wikipedia

    en.wikipedia.org/wiki/Rare-earth_element

    The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.

  7. Yttrium barium copper oxide - Wikipedia

    en.wikipedia.org/wiki/Yttrium_barium_copper_oxide

    Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds that display high-temperature superconductivity; it includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen [77 K (−196.2 °C; −321.1 °F)] at about 93 K (−180.2 °C; −292.3 °F).

  8. Yttrium aluminium garnet - Wikipedia

    en.wikipedia.org/wiki/Yttrium_aluminium_garnet

    Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP [2]) in a hexagonal or an orthorhombic, perovskite-like form, and the monoclinic Y 4 Al 2 O 9 (YAM [3]).

  9. Transparent ceramics - Wikipedia

    en.wikipedia.org/wiki/Transparent_ceramics

    Further development of yttrium ceramic nanomaterials was carried out by General Electric in the 1970s in Schenectady and Cleveland, motivated by lighting and ceramic laser applications. [28] Yttralox, transparent yttrium oxide Y 2 O 3 containing ~ 10% thorium oxide (ThO 2) was fabricated by Greskovich and Woods. [29]
