摘　　要：国产氧化铝中K_2O和Li_20含量严重偏高,致使细粒级-45μm含量偏高,氧化铝为粉状。当粉状氧化铝添加到电解槽之后,电解质中的LiF和KF含量严重偏高,且电解质易形成漂浮状态,降低了电解槽的电流效率。K20 and Li20 contents in domestic alumina are seriously high, fine particles -45μm, and alumina is actually powder. When alumina is duction cell, the electrolyte contents of LiF and KF become seriously high, formed a floating state, it is severely reducing the cell＇s current efficiency. resulting in higher levels of added into the aluminum re- and the electrolyte are easily

关 键 词：氧化铝 物理化学性能 铝电解 电流效率
