Yttrium is a chemical element; it has symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". [8] Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals and is never found in nature as a free ...
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 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).
The flame test carried out on a copper halide.The characteristic bluish-green color of the flame is due to the copper. A flame test is relatively quick test for the presence of some elements in a sample.
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 ...
