混合稀土氧化物在冰晶石—氟化铝—氧化铝系熔体中的溶解度数据,对于当前在铝电解槽上加入混合稀土氧化物直接生产含混合稀土的铝合金(成品合金与中间合金)更有现实的意义。显然,不了解溶解度的数值,就无法控制它的加入量,而为了生产稀土含量不同的铝合金,需要控制电解质中的Al_2O_3/REO之比。了解在一定条件下(一定的温度、氧化铝浓度与分子比等)电解质
Solubility data of mixed rare earth oxides in cryolite-aluminum fluoride-alumina based melts. For the current production of mixed rare earth oxides (finished alloys and master alloys) by adding mixed rare earth oxides on an aluminum reduction cell Realistic meaning. Obviously, without understanding the value of solubility, it can not control the amount of its addition, and in order to produce different content of rare earth aluminum alloy, you need to control the electrolyte Al_2O_3 / REO ratio. Understand under certain conditions (a certain temperature, alumina concentration and molecular ratio, etc.) electrolyte
