Yttrium and pnictides can form compounds with the chemical formula YE (E = N, P, As, Sb). They can be hydrolyzed in humid air and emit volatile hydrides EH 3. Yttrium and carbon can form a variety of compounds, such as Y 2 C 3, [9] YC 2. [10] They can be made in several ways: 2 Y + 3 C → Y 2 C 3 Y 2 O 3 + 7 C → 2 YC 2 + 3 CO ↑
Y 2 O 3 is a prospective solid-state laser material. In particular, lasers with ytterbium as dopant allow the efficient operation both in continuous operation [ 6 ] and in pulsed regimes. [ 7 ] At high concentration of excitations (of order of 1%) and poor cooling, the quenching of emission at laser frequency and avalanche broadband emission ...
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 monoxide.
Yttrium, iron, aluminium, and gadolinium garnets (e.g. Y 3 (Fe,Al) 5 O 12 and Y 3 (Fe,Gd) 5 O 12) have important magnetic properties. [15] YIG is also very efficient as an acoustic energy transmitter and transducer. [74] Yttrium aluminium garnet (Y 3 Al 5 O 12 or YAG) has a hardness of 8.5 and is also used as a gemstone in jewelry (simulated ...
Yttrium(III) nitrate is mainly used as a source of Y 3+ cations. It is a precursor of some yttrium-containing materials, such as Y 4 Al 2 O 9, [3] YBa 2 Cu 3 O 6.5+x [2] and yttrium-based metal-organic frameworks. [5] It can also be used as a catalyst in organic synthesis. [6]
Chlorine – CL (chemical symbol) Chromosome – X or Y; Church – CH or CE (Church of England) or RC (Roman Catholic) Circa – C; Circle – O (the letter O is a circle) City – NY , LA (Los Angeles), or EC (postcode for City of London) Closed - TO (like a door) Club – Y
The structure of these materials depends on the oxygen content. This non-stoichiometry is denoted by the x in the chemical formula YBa 2 Cu 3 O 7−x. When x = 1, the O(1) sites in the Cu(1) layer (as labelled in the unit cell) are vacant and the structure is tetragonal. The tetragonal form of YBCO is insulating and does not superconduct.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
