Abstract

The electrical conductivity of fluid selenium has been measured as a function of temperature and pressure to 1750°C and 1200 bars, respectively. The conductivity isobars exhibit strong increases to nearly-metallic behaviour in selenium above 1300°C at supercritical pressures. As the fluid is heated above 1500-1600°C the conductivity isobars drop sharply toward more insulating behaviour in the pressure range investigated here.
