Relatively little is known about the basic physical chemistry of even simple molten salt systems. This communication reports data for the solubilities of Na2CO3 and K2CO3 in molten sodium nitrate/potassium nitrate eutectic at temperatures between 520 and 620 K. Values of the Gibb's free energy, enthalpy and entropy of solution have been calculated from these results.

Heat Transfer Fluids

In this study energetic and exergetic performances of parabolic trough collector is theoretically investigated by using 120 l/min synthetic ‘’Dowtherm A’’ oil , 1200 l/min Air at 100 bar (10 MPa) and 150 l/min molten salt which is mixture of 60 wt% sodium nitrate (NaNO3) and 40 wt% potassium nitrate (KNO3) which are widely used as heat transfer fluids. Fluids performance comparisons were performed with the LS-2 module, which is used with vacuum in annulus and Cermet as a selective coating. LS-2 module has 7.8 m receiver length and is 39 m2 aperture area. As a result, the maximum exergy efficiency of the molten salt, synthetic oil, Air to be 41.19% at 422 °C, 40.82% at 400 °C, 40.33% at 402 °C, respectively. The maximum exergy of air is higher than other working fluids up to 310 ° C but after about 310 ° C the exergy of the molten salt is higher than the others. The molten salt has the best energy efficiency at its operating temperatures (250 °C to 550 °C) than other working fluids.

The influence of different molten salt environments on formation of tungstates has been studied. Well crystalline and pure Bi2WO6 have been prepared in potassium nitrite KNO2 (350°C), potassium chloride KCl (800°C) and mixture of potassium-sodium sulphates K2SO4-Na2SO4 (800°C), but ZnWO4 have been successfully synthesized in sodium nitrate NaNO3 (350°C), mixture of sodium-potassium chlorides NaCl-KCl (680°C), potassium chloride KCl (780°C) and mixture of potassium-sodium sulphates K2SO4-Na2SO4 (850°C). The higher surface area and photocatalytic activity show powders prepared at lower temperature.
