摘　　要：本文在实验室条件下,研究了氧化铝中Li、K、Ca对电解质初晶温度和电解槽热平衡的影响,应用响应曲面法,建立了Na_(3)AlF_(6)-Al_(2)O_(3)-LiF-KF-CaF_(2)五元系初晶温度数学模型,得出结论:在实验条件范围内,对于电解质初晶温度的影响大小依次为:LiF的主效应>分子比的主效应>KF的主效应>CaF_(2)的主效应。The effect of Cryolite Ratio and content of LiF,KF,CaF_(2) on liquidus temperature is researched in laboratory.The results show that liquidus temperature is increased with increasing of Cryolite Ratio and liquidus temperature is decreased with increasing of the content of LiF,KF,CaF_(2).Liquidus temperature of system of Na_(3)AlF_(6)-Al_(2)O_(3)-LiF-KF-CaF_(2) is simulated with the method of response surface.From the figure of response surface,it is shown that the ability of effect on liquidus temperature is:LiF>CR>KF>CaF_(2).
