Yttrium oxide, also known as yttria, is Y 2 O 3. It is an air-stable, white solid substance. The thermal conductivity of yttrium oxide is 27 W/(m·K). [5] Applications
A good example is yttrium(III) oxide (Y 2 O 3), also known as yttria, a six-coordinate white solid. [22] Yttrium forms a water-insoluble fluoride, hydroxide, and oxalate, but its bromide, chloride, iodide, nitrate and sulfate are all soluble in water. [14] The Y 3+ ion is colorless in solution due to the absence of electrons in the d and f ...
This ability to conduct O 2− ions makes yttria-stabilized zirconia well suited for application as solid electrolyte in solid oxide fuel cells. For low dopant concentrations, the ionic conductivity of the stabilized zirconias increases with increasing Y 2 O 3 content. It has a maximum around 8–9 mol% almost independent of the temperature ...
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).
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 oxide. Yttrium hydroxide can be precipitated by the reaction of soluble yttrium compounds with sodium hydroxide or ammonia, and can also be obtained by the hydrolysis of yttrium ...
Yttrium iron garnet (YIG) is a kind of synthetic garnet, with chemical composition Y 3 Fe 2 (FeO 4) 3, or Y 3 Fe 5 O 12. It is a ferrimagnetic material [1] with a Curie temperature of 560 K. [2] YIG may also be known as yttrium ferrite garnet, or as iron yttrium oxide or yttrium iron oxide, the latter two names usually associated with powdered ...
