In-situ Raman spectroscopic analysis of phase transition temperatures in silica interacting with water and NaCl solutions

Abstract Phase transition temperatures of pure water and aqueous sodium chloride (NaCl) solutions, both in bulk form and mixed with the silica (SiO2) powder, were investigated using in-situ Raman spectroscopy. To determine the freezing and melting temperatures, the OH-stretching and bending regions...
