Abstract：The activity of La_2O_3 in liquid La_2O_3-CaF_2 and La_2O_3-CaF_2-CaO-SiO_2 slagshas been determined at 1500℃ y equilibrating the slags with liquid tin in agraphite crucible under one atmosphere of carbon monoxide. From the ctivitydata on the La_2O_3-CaF_2 system, the activity of CaF_2 has been obtained by Gibbs-Duhem integration. The activity ata on the above mentioned slags are briefly discussed on thebasis of ionic constitution of liquid slags. 收稿日期: 1980-02-18      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 王常珍 邹元爔 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1980/V16/I2/190 [1] 王渭源,邹元爔,金属学报,6(1963) ,40． [2] 邹元爔,赵彭年,曹兆民,金属学报,6(1963) ,121． [3] Chou Yuan-hsi (邹元爔), Chow Ji-Cheng (周继程), Chao Peng-nian (赵彭年), Sci.
