It is composed of some polynomials of excess mole free energies versus content variable. a group of parameters is included in the polynomials. along with the reliable known thermodynamic properties associating the homogeneous region the parameters can be evaluated. and then the component activities in that region are possible to be predicated. This paper is devoted to illustrate the applications of SELF-SReM4 for molten slag of MnO-SiO2-al2O3-CaO and its sub-ternary systems. The evaluated results were very close to those of slag-metal equilibrium experiments and the Chipman's and Pelton's results. Key words： SELF-SReM4 model    MnO-SiO_2-Al_2O_3-CaO system    calculation of component activity 收稿日期: 1997-10-18      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 张晓兵 蒋国昌 徐匡迪 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1997/V33/I10/1085 1 Masson V R. 2nd Intern Confon Melten Fluxes and Slags, Lake Tahoe, 1984; 3 2 万谷郎,日野光兀,铁钢,1988, 74;1701 3 Pelton a D, Blander M. 2nd Intern Con fon Melten Fluxes and Slagr, Lake Tahoe, 1984;281 4 Kriksson G, Pelton a D.
