Compressibilities of the Molten Alkali Nitrates and Silver Nitrate at High Pressure

Abstract

The densities of the pure molten salts LiNO₃, NaNO₃, KNO₃, RbNO₃, and AgNO₃ were determined by the piston—cylinder method at pressures up to 9000 atm. The temperature covered by the measurements was from just above the liquidus curves up to about 500°C. The results were related to the corresponding‐states theory of fused salts. In the case of LiNO₃, deviation from the corresponding‐states law was ascribed to anion—anion contact.
