Experimental determination of the resistivity limits for platinum and iron metal gases using an exploding wire

Abstract

Transport properties of metals in solid, liquid, gas or plasma phases are an open area of research, both theoretically and experimentally. Concretely, there are no measurements available for the resistivity of gas phase of metals. In the latter case, the use of exploding wire systems allows one to reach states from solid to plasma that are not accessible with other experimental methods. In this work, following a measurement method previously used with copper, experimental resistivity limits of iron and platinum metal gases are presented based on measurements performed on the metal gas expansion phase.
