摘　　要：借助于在实验室电解槽上制得的渗透了金属钠的炭质试样研究金属钠与冰晶石溶体的反应，实验研究结果得出，在酸性冰晶石熔体中，金属钠与冰晶石熔体反应生成金属铝；而在碱性冰晶石熔体中，金属钠与冰晶石焙体的反应产物为Ｎａ２Ｆ。根据金属钠与冰晶石熔体的反应，讨论了当金属铝投入透明的电解质熔体中时。Some samples penetrated with sodium in a laboratory-scale aluminum electrolysis cell were used to study the reaction of sodium with cryolite melt.The experimental results showed that the metallic aluminum formed in acidic cryolite melt,and Na 2F formed in basic cryolite melt.When a piece of aluminum was added tocryolite melts fog-like metals occurred,the nature of which was discussed according to the above-mentioned reactions.
