采用同位素饱和平衡法,在1550～1700℃之间测定了Nb在CaO-SiO_2,SiO_2-MnO-Fe_2O_3-Al_2O_3-Nb_2O_5渣和铁之间的分配系数。结果得到了温度与分配系数的关系式分别为。lgL=184800╱4.575T-18.7及lgL=176500╱4.575T-18.4。文中对试验结果与前人所作工作进行了比较和讨论。
The distribution coefficients of Nb between slag and iron of CaO-SiO_2, SiO_2-MnO-Fe_2O_3-Al_2O_3-Nb_2O_5 were measured by isotope saturation balance method at 1550 ~ 1700 ℃. The results obtained the relationship between temperature and partition coefficient are. lgL = 184800 ╱ 4.575T-18.7 and lgL = 176500 ╱ 4.575T-18.4. The paper compares the results of the experiment with the previous work.
