Rankinite subsequently reacts with calcium oxide to form dicalcium silicate and reacts with fayalite to form wollastonite. These reactions can be represented as follows:2(2FeO. SiO_2)+3CaO=3CaO·2SiO_2+4FeO,3CaO·2SiO_2+CaO=2(2CaO·SiO_2),3CaO·2SiO_2+2FeO·SiO_2=3(CaO·SiO_2)+2FeO.The reduction of fayalite is also discussed. 收稿日期: 1964-03-18      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 陈钧珊 周炘祥 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1964/V7/I3/221 [1] #12 [2] #12 [3] #12 [4] #12 [5] 1952． [6] Bowen, N.
