Abstract:Water-NaCl solid solutions with the salt weight fraction p = 0.0001–0.1000 subjected to high uniaxial compression exhibit elastic instability (similar to the Bridgman explosive effect) in the temperature range 100–260 K. At temperatures from 225 to 260 K, stability threshold p c (or a critical pressure at which the explosive instability occurs) of these solutions is equal to, or higher than, p c for pure water ice. However, in the temperature interval 100–225 K, thresholds p c for the NaCl-water solid solutions with p ≥ 0.001 are anomalously low. The largest drop of p c (by 15 to 30 times relative to p c for pure water ice) is observed for low p, 0.001 ≤ p ≤ 0.010. The possible structure of the solid ice solutions in all the temperature ranges mentioned above is analyzed in terms of the percolation theory as applied to elastic networks.
