Abstract

Phase composition and structural properties of ionic systems in the LiNO₃–KNO₃ binary eutectic system with various concentrations of LiClO₄ as well as nanometer-sized γ-Al₂O₃ powder were studied by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). It was found that an increase in the LiClO₄ content in the initial mixture results in a decrease in the KNO₃ fraction, which confirms the assumption about the exchange reaction between potassium nitrate and lithium perchlorate with the formation of KClO₄ and LiNO₃. It was confirmed that in the composites with potassium nitrate and nanoscale γ-Al₂O₃, a metastable R3m phase KNO₃ is formed, which is nanoscale and rather stable.
