The density of zirconium hydride varies based the hydrogen and ranges between 5.56 and 6.52 g cm −3. Even in the narrow range of concentrations which make up zirconium hydride, mixtures of hydrogen and zirconium can form a number of different structures, with very different properties.
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.

The Enron Egg is a "compact nuclear reactor that uses Uranium-Zirconium Hydride (U-ZrH) fuel rods to generate heat through nuclear fission," according to the Enron website. "This heat is ...
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.
Schwartz's reagent is the common name for the organozirconium compound with the formula (C 5 H 5) 2 ZrHCl, sometimes called zirconocene hydrochloride or zirconocene chloride hydride, and is named after Jeffrey Schwartz, a chemistry professor at Princeton University.
Metal hydride-oxidizer mixtures replace the metal with its corresponding hydride. They are generally safer to handle than the corresponding metal-oxidizer compositions. During burning they also release hydrogen, which can act as a secondary fuel. Zirconium hydride, titanium hydride, and boron hydride are commonly used.
