Thermophysical properties of the equimolar mixture NaNO/sub 3/-KNO/sub 3/ from 300 to 600/sup 0/C
The equimolar molten salt mixture NaNO/sub 3/-KNO/sub 3/ is being proposed as a heat-transfer fluid and thermal-energy storage medium for various solar energy applications. In these applications the maximum operating temperature will be in the range 500 to 600/sup 0/C. Industrial experience and previous experimental investigations on this molten salt mixture have generally been confined to temperatures below 450/sup 0/C. In order to provide data to solve various specific design problems associated with the use of these molten nitrate salts as heat transfer fluids, it is important to know how the physical properties of these salts are affected by temperature and composition of the liquid and gas phases. The viscosity, surface tension, and density data measured over the temperature range 300 to 600/sup 0/C are presented and discussed.
