Liquidus temperature is a crucial parameter in aluminum electrolysis, impacting current efficiency and energy consumption. This study presents a novel approach to measure the liquidus temperature of molten cryolite-based aluminum electrolytes using an Agilent 34401A meter linked to computer software for control. The liquidus temperatures of NaF and NaCl were analyzed for comparison, demonstrating that this method is both convenient and accurate, with a margin of error of ±1~1.5℃ within the range of 801 to 995℃. The research also explores the effects of added compounds on the liquidus temperature, highlighting that incorporating NaCl and LiF significantly reduces the liquidus temperature of the electrolyte system composed of NaF·AlF3, Al2O3, CaF2, and LiF. A mathematical model was derived to describe this relationship, expressed as T(℃)=947.588 - 5.907×LiF(wt/%) - 6.223×NaCl(wt/%). The findings aim to provide a scientific foundation for selecting low-temperature aluminum electrolyte compositions, thus benefiting industrial production processes in aluminum electrolysis.
