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 ...
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 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(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 ...
Yttrium oxalate is highly insoluble in water and converts to the oxide when heated. [6] Yttrium oxalate forms crystalline hydrates (colorless crystals) with the formula Y 2 (C 2 O 4) 3 •n H 2 O, where n = 4, 9, and 10.
Ytterbium(III) oxide and its crystal structure. Ytterbium reacts with oxygen to form ytterbium(III) oxide (Yb 2 O 3 ), which crystallizes in the "rare-earth C-type sesquioxide" structure which is related to the fluorite structure with one quarter of the anions removed, leading to ytterbium atoms in two different six coordinate (non-octahedral ...
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 ...
Yttrium(III) sulfate is an inorganic compound with the formula Y 2 (SO 4) 3. The most common form is the anhydrate and octahydrate. The most common form is the anhydrate and octahydrate. Reactions
