The results for 1600℃ thus obtained are believed to be more reasonable and trustworthy than previous investigations. An attempt has also been made to develop a graphical method for the analysis of data. By this means, some relatively accurate iso-activity curves of CaO have been obtained, and values of CaO activities in a wide range of composition in this melt can easily be obtained from the figures derived from experimental data by the authors. Inaddition, the amphoteric behaviour of Al_2O_3 has been determined quantitatively, and the results are believed to have practical significance in blast furnace smelting using high alumina slags. 收稿日期: 1986-03-18      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 张子青 周继程 邹元燨 田彦文 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I3/76 1 Rein, R.H.; Chipman, J., Trans.
