Abstract
By means of Brillouin scattering spectroscopy, hypersonic velocities in NaNO3-KNO3 binary melts have been measured at temperatures from the liquidus temperatures of the melts to 200 K above them over the entire range of compositions. The light beam scattered by the melt is analyzed with a pressure-scanned Fabry-Perot spectrometer. The hypersonic velocities obtained are about the same as the ultrasonic velocities reported at compositions rich in NaNO3, but are markedly larger than those at compositions rich in KNO3, indicating the occurrence of structural relaxation. Thermodynamic values such as adiabatic and isothermal compressibilities, constant-volume heat capacity, and internal pressure calculated from the sound velocity obtained show that the melt can be treated as a typical ionic liquid, though it contains a certain amount of associated species.
