From the equilibrium data obtained, the activity coefficients of calcium in the aforementioned liquid metals have been evaluated. It has been found that the calcium content of the liquid metals in equilibrium with calcium carbide and graphite increases as the temperature is lowered. Of the three metals studied, tin has been found to contain the highest amount of calcium under the same equilibrium conditions. These findings may prove useful in the commercial production of Pb-Ca and Sn-Ca alloys by the calcium carbide process. 收稿日期: 1964-02-18      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 郑文陞 邹元爔 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1964/V7/I2/130 [1] 中南矿冶学院:有色重金属冶金学,(冶金工业出版社,1959年),中册,226-232頁,下册,140-142頁.
