The electrical conductance of fused sodium nitrate to 475 °C and 12 kbars
The electrical conductance of fused sodium nitrate has been measured in a piston-cylinder pressure apparatus between 320 and 475 °C to pressures of 12 kbars. The value of the activation volume for the specific conductance [math] equals 2.5 cm3/mole at 380 °C and is almost independent of temperature. Using PVT-data for sodium nitrate, isochoric activation energies have been calculated from measured isobaric activation energies
The structure of molten
High energy photon diffraction measurements on molten ZnCl2 have been carried out in the temperature range 623â853 K. The momentum transfer range covered is 0.15 Ă

â1. The sample is investigated in transmission geometry. The data are in good agreement with neutron diffraction measurements. A discrepancy at smaller Q values is to be noted, however, with earlier studies using conventional MoâKα X-rays in reflection geometry. By combining neutron and high energy photon results, the partial distribution functions can be separated to some extent. Almost no change of the first ZnâCl distance is observed with increasing temperature, whereas the distribution of the first shell ClâCl distances increases in width and the first shell ZnâZn distance decreases
