The research investigates the density characteristics of KF-AlF3 melts with various ratios of KF and AlF3, including additives such as Al2O3 and AlPO4. The objective of the study is to provide a comprehensive analysis of the influence of these additives on the density and molar volume of the melts. Using the Archimedean method, density measurements were conducted, allowing for the subsequent calculation of the molar volumes. Results indicate that the molar volumes decrease in correlation with the concentration of Al2O3 or AlPO4 present in the melts. Notably, in the system incorporating AlPO4, a significant relationship was identified between cryolite ratios (CRs) and the slopes of the molar volume trend lines, achieving a high correlation factor of R2 = 0.9844. Conversely, in systems with Al2O3, a distinct discontinuity is observed at a CR of 2.5, suggesting varying physicochemical interactions depending on the additive composition. This study contributes valuable insights into the thermal and physicochemical behavior of low-temperature aluminum electrolysis technologies, particularly concerning the optimization of electrolyte compositions.
