根据工业实际情况,研究了稀土在冰晶石(rNaF·AIF_3)-混合轻稀土氧化物(REO)熔体与铝液间的平衡问题.考察了各种因素对稀土在合金与熔盐两相中平衡浓度的影响.给出了两相中稀土平衡浓度与各种因素的关系式,并考察了铝加入量及试样中稀土氧化物含量对稀土还原率的影响.
According to the actual situation of industry, the balance of rare earths in cryolite (rNaF · AIF_3) -mixed rare earth oxide (REO) melt and aluminum liquid was studied.The effects of various factors on the corrosion behavior of rare earth in the alloy and molten salt phase Equilibrium concentration.The relationship between rare earth equilibrium concentration and various factors in two phases was given.The influence of the amount of aluminum added and the content of rare earth oxide in the sample on the reduction rate of rare earth was also investigated.
