The results are summarized as follows: 1. Temperature dependence of desulphurization constant for the formation of Y-S_(S) as the equilibrium phase in the temperature range of 1500—1600℃ is given by lg K_(YS)=47000/T+20.86 2. Temperature dependences of the first activity interaction parameters between Y and S in liquid Ni are determined to be e_S~Y=350200/T+179 in the temperature range of 1500—1600℃. 3. Temperature dependence of the standard free energy of formation of YS_(S) in liquid Ni is derived to be [Y]_(Ni)+[S]_(Ni)=YS_(S) △G°=-215000+95.53T cal/mol 4. Temperature dependence of the standard free energy of solution of Y in liquid Ni is derived to be Y_(1)=[Y]_(Ni) △G°=126200-79.31T cal/mol 5. Temperature dependences of activity coefficient and selfinteraction coefficient of Y in liquid Ni are derived to be lgγ_Y~0=27584/T-15.151 ∑_Y~Y=-127052/T+69.79 e_Y~Y=-364.8/T+0.2018 6. The minimum content of S in equilibria with Y in liquid Ni in the temperature range of 1500-1600℃ are given ~*[％S]=0.002-0.005 and ~*[％Y]=0.005-0.020. The S content raises with Y when exceed this minimum point. 收稿日期: 1984-04-18      基金资助:中国科学院科学基金 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 王龙妹 杜挺 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I4/286 1#12 2 Jacquemot, A.; Gattlier, C., Rapport IRSID, PCM RP, № 63, (1973) . 3 Ejima, A; Suzuki, K-I; Harada, N.; Sanbongi, K., Trans.
