The free energy of the reaction 3(CaC_2)+2[As]=(Ca_3As_2)+6[C] is found to be △G°=-88150+29.80T(J), both As and Ca_3As_2 based on the infinitely dilute or 1% by weight solution standard. A plot of 1g fCα_3As_2 νS (%Ca_3As_2) gives values of the activity coefficient of Cα_3As_2. From the experimental equilibrium data of the quarternary system Fe-As-C-j where j=Si, Mn, P, values of 1g f_(As)~j can thus be evaluated. The interaction coefficients of the activity of As in iron melts e_(As)~j, are thus obtained as follow: e_(As)~(Si) e_(As)~(Mn) e_(As)~P 1350℃ 0.064 -0.035 0 1600℃ 0.057 -0.031 0 收稿日期: 1986-06-18      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 董元篪 魏寿昆 彭(忄育)强 朱元凯 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I6/89 1 不破祐;藤倉正国;的埸幸雄,铁钢,46(1960) ,235． 2 Banya, S.; Chipman, J,, Trans.
