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 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 ...
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 ...
This group is determined by adding the salt in water and then adding dilute hydrochloric acid (to make the medium acidic) followed by hydrogen sulfide gas. Usually it is done by passing hydrogen sulfide over the test tube for detection of 1st group cations. If it forms a reddish-brown or black precipitate then Bi 3+, Cu 2+, Hg 2+ or Pb 2+ is ...
Nitric oxide from copper turnings and diluted nitric acid; Nitrogen dioxide from copper turnings and concentrated nitric acid; Ammonia from magnesium nitride and water, deuterated ammonia when heavy water is used; [1] also from calcium oxide and solution of ammonium chloride; Carbon monoxide from pumice impregnated with oxalic acid and ...
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(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 ...
