WebNov 1, 2024 · Hydrides with experimentally verified superconductivity Table 1 summarizes most of the superconducting binary hydrides with their predicted/measured maximum T c at the corresponding pressure. As highlighted in red, many of the hydrides have already been experimentally shown to be superconductors with T c s up to 262 K [ 53, 54 ]. WebCovalent hydrides are primarily compounds of hydrogen and nonmetals, in which the bonds are evidently electron pairs shared by atoms of comparable electronegativities. For example, most nonmetal hydrides are volatile compounds, held together in the condensed state by relatively weak van der Waals intermolecular interactions (see chemical bonding). …
