Electrons in liquid metals

DEC 01, 1966

After more than a century of experimental study, an explanation of the electrical properties of liquid metals is now available. Concepts such as “nearly free electrons,” “pseudopotentials” and “pseudo‐atoms” have helped to solve the problem. But an exact description of what happens when the orderly solid crystal melts into the disordered liquid remains a challenge.

EXCELLENT DETERMINATIONS of the electrical conductivity of liquid mercury were made by Matthiessen, Siemens and others in the early 1860’s; it is a measure of the vitality of this branch of science that the explanation of the magnitude of this familiar physical constant is still controversial; until five years ago, we could not even explain its order of magnitude.
