重稀土元素钇在铁、镍液中的脱氧热力学的研究甚少;Bek Z.曾采用间接法测得1600℃铁液中K_(Y_2O_2)=9.5×10~(-20),等由热力学计算出1600℃镍液中K_(Y_2O_2)=2.4×10~(-11)。本文采用浓差定氧和低温无水分离稀土夹杂物电解技术分别研究了1575～1625℃铁液及1500～1600℃镍液中[Y]—[O]平衡,测得钇的脱氧常数和钇与氧相互作用系数与温度的关系。试验用0号纯镍成分(wt％)如下:Ni 99.99、S 0.0005、
There are few studies on the thermodynamics of deoxidation of heavy rare earth element yttrium in iron and nickel solution. Bek Z. The K_ (Y_2O_2) = 9.5 × 10 ~ (-20) Out of 1600 ℃ nickel solution K_ (Y_2O_2) = 2.4 × 10 ~ (-11). In this paper, the equilibrium of [Y] - [O] in 1575 ~ 1625 ℃ molten iron and 1500 ~ 1600 ℃ nickel solution was studied respectively using concentration of oxygen and low temperature anhydrous rare earth inclusion electrolysis technology. The deoxidation constants of yttrium and yttrium Relationship between oxygen interaction coefficient and temperature. The pure nickel component (wt%) for test No. 0 is as follows: Ni 99.99, S 0.0005,
