metallic hydrogen [mə′tal·ik ′hī·drə·jən] (physical chemistry) A phase of hydrogen believed to occur at extremely high pressures, in which the material transforms to a conducting molecular solid. A phase of hydrogen believed to occur at still higher pressures, in which the molecular bonds that exist at lower pressures are broken and an atomic solid with the structure of an alkali metal is formed.

Metallic hydrogen may be a superconductor at room temperature. Then, in 1968, Ashcroft suggested that if metallic hydrogen could be stably produced, it might behave as a superconductor. Anyone interested in using metallic hydrogen as a compact fuel for nuclear fusion reactors, or in exploring the possibility that metallic hydrogen may even be a superconductor, will have to wait until researchers can further untangle the remarkable complexity of this simplest of all elements. |
