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 ...
Yttrium is a key ingredient in the yttrium barium copper oxide (YBa 2 Cu 3 O 7, aka 'YBCO' or '1-2-3') superconductor developed at the University of Alabama in Huntsville and the University of Houston in 1987. [49] This superconductor is notable because the operating superconductivity temperature is above liquid nitrogen's boiling point (77.1 K ...
Yttrium(II) oxide or yttrium monoxide is a chemical compound with the formula YO. This chemical compound was first created in its solid form by pulsed laser deposition, using yttrium(III) oxide as the target at 350 °C. The film was deposited on calcium fluoride using a krypton monofluoride laser. This resulted in a 200 nm flim of yttrium ...
Organoyttrium chemistry is the study of compounds containing carbon-yttrium bonds. These compounds are almost invariably formal Y 3+ derivatives, are generally diamagnetic and colorless, a consequence of the closed-shell configuration of the trication. [2] Organoyttrium compounds are mainly of academic interest.
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 ...
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 ...
Scientists have long surmised that rusty iron oxide is what made Mars red: Thanks to the fleet of spacecraft that have studied Mars over the past few decades, scientists knew that the red color is ...
Yttrium oxalate is an inorganic compound, a salt of yttrium and oxalic acid with the chemical formula Y 2 (C 2 O 4) 3. [3] The compound does not dissolve in water and forms crystalline hydrates—colorless crystals.
