Resumo
The extended corresponding-states principle has been applied to pure molten alkali halides for the calculation of viscosity and thermal conductivity. The model uses temperature-dependent equivalent substance reducing ratios (ESRR) to insure conformality among the various molten salts, with sodium chloride as the reference salt. The ESRR were found along the saturation boundary from saturated liquid density and vapour pressure data of the salts of interest and of the reference salt. These ESRR were then used to calculate the thermal conductivity and viscosity for the salts of interest, in the liquid state. Calculations were also made with the simple two-parameter corresponding-states principle, with melting temperature and the corresponding density as scaling factors. Agreement between calculated and experimental data is within 10% for viscosity, and within experimental accuracy for thermal conductivity, for most of the salts studied.
