Accurate measurements and possible fine structure in the properties of liquid metals Conference Paper uri icon

abstract

  • High accuracy measurements of physical properties of liquid tin and bismuth to 1300K have been made. These include nuclear gamma-ray attenuation measurements of the density, pulse-echo measurements of the speed of sound and four probe measurements of the electrical conductivity. Tin was chosen as a relatively simple metal while bismuth is known for its complex behaviour in the liquid state. For bismuth we revealed a rich structure of the temperature dependence of these physical properties in the liquid phase. More surprisingly we also found deviations from the expected smooth temperature dependence in tin. An attempt is made to provide a physical interpretation for these results.
