High-pressure thermophysical properties of solid and liquid uranium

Abstract

The thermophysical properties of solid and liquid uranium have been studied up to 3300 K under a 0.12 GPa static pressure by using the isobaric expansion experiment (IEX). The submillisecond heating dynamic technique has been used to investigate measurements such as enthalpy, volume expansion, electrical resistivity and sound velocity. Uranium exhibits a 2.5% volume expansion at melting and the sound velocity in the liquid state seems to remain constant as a function of temperature (or density).
