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 ...
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 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 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).
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(III) nitrate hexahydrate loses crystallized water at relatively low temperature. Upon further heating, basic salt YONO 3 is formed. [2] At 600 C, the thermal decomposition is complete. Y 2 O 3 is the final product. [3] Y(NO 3) 3 ·3TBP is formed when tributyl phosphate is used as the extracting solvent. [4]
Yttrium(III) hydroxide can be produced by reacting yttrium(III) nitrate and sodium hydroxide in aqueous solution: [1] Y(NO 3) 3 + 3 NaOH → Y(OH) 3 ↓ + 3 NaNO 3. This gives yttrium(III) hydroxide as a white gelatinous precipitate, which can be dried to a white powder. [2]
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.
