WebMetal hydrides are considered a promising means of hydrogen storage mainly because they store hydrogen at low pressure while having volumetric densities comparable to liquid hydrogen ( Reilly, 1979 ). Furthermore, the release of hydrogen in metal hydrides being an endothermic process, this makes them inherently safe. WebResults showed that hydrides formed in well-annealed samples after electrolytic hydrogen charging, but a new phase in the cold-deformed samples was not observed. The …

Web27 sep. 2016 · The saline hydrides are generally considered those of the alkali metals and the alkaline-earth metals (with the possible exception of beryllium hydride, BeH2, and magnesium hydride, MgH2). These metals enter into a direct reaction with hydrogen at elevated temperatures (300–700 °C [570–1,300 °F]) to produce hydrides of the general …

Many transition metals form compounds with hydrogen, called binary hydrides: binary, because these compounds contain only two elements, and hydride, because the hydrogenic ligand is assumed to have hydridic (H -like) character. These compounds are invariably insoluble in all solvents, reflecting their polymeric structures. They often exhibit metal-like electrical conductivity.
