Zirconium(II) hydride is a molecular chemical compound with the chemical formula Zr H 2.It is a grey crystalline solid or dark gray to black powder. [4] [5] It has been prepared by laser ablation and isolated at low temperature.
Similar to other metal hydrides, different crystalline phases of zirconium hydrides are conventionally labeled with Greek letters, and α is reserved for the metal. The known ZrH x phases are γ (x = 1), δ (x = 1.5–1.65) and ε (x = 1.75–2).
The following list of accelerator mass spectrometry facilities includes research centers that employ accelerator mass spectrometry (AMS). Accelerator mass spectrometry is a form of mass spectrometry that accelerates ions to extraordinarily high kinetic energies before mass analysis.
Uranium zirconium hydride (UZrH, U-ZrH x), a dispersion of metallic uranium in a δ-ZrH 1.6 matrix, is used as the fuel in TRIGA reactors. [1] UZrH fuel is used in most research reactors at universities and has a large, prompt negative fuel temperature coefficient of reactivity, meaning that as the temperature of the core increases, the reactivity rapidly decreases.
α-Methylstyrene (AMS) is an organic compound with the formula C 6 H 5 C(CH 3)=CH 2. It is a colorless oil. [4] Synthesis and reactions.
This reaction also affords (C 5 H 5) 2 ZrH 2, which is treated with methylene chloride to give Schwartz's reagent [3] An alternative procedure that generated Schwartz's reagent from dihydride has also been reported. [4] Moreover, it's possible to perform an in situ preparation of (C 5 H 5) 2 ZrHCl from zirconocene dichloride by using LiH.
