ilica nanoparticles (1% by weight) were dispersed in a eutectic f lithium carbonate and potassium carbonate (62:38 ratio) to btain high temperature nanofluids. A differential scanning caloimeter instrument was used to measure the specific heat of the eat molten salt eutectic and after addition of nanoparticles. The pecific heat of the nanofluid was enhanced by 19–24%. The meaurement uncertainty for the specific heat values in the experients is estimated to be in the range of 1–5%. These experimental ata contradict earlier experimental results reported in the literaure. (Notably, the stability of the nanofluid samples was not veried in these studies.) In the present study, the dispersion and tability of the nanoparticles were confirmed by using scanning lectron microscopy (SEM). Percolation networks were observed n the SEM image of the nanofluid. Furthermore, no agglomeraion of the nanoparticles was observed, as confirmed by transmision electron microscopy. The observed enhancements are sugested to be due to the high specific surface energies that are ssociated with the high surface area of the nanoparticles per unit olume (or per unit mass).
