The chief phase, containing sodium aluminosilicate hydrate, has been identified to be hydroxy-sodalite crystals, usually having defect structure with vacancies of silicon atoms on the skeleton of sodalite lattice. Key words： Na-Al silicate slime    hydroxy-sodalite    silicon atom vacancy      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 邓红梅 曾文明 陈念贻 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1996/V32/I12/1248 1陈念贻.氧化铝生产的物理化学.上海:上海科学技术出版社,19622FuldaW,GinsbergH．TonerdeundAluminium．Berlin:WalterdeGruyter&Co,19513BA,TA,1975;3:6594RegisAJ,SandLB,CalmonC,GilwoodME．JPhyschem,1960;64:15675LiuMiaoxiu,ZhouPeifang,ChenNianyi,LiYu,KeJiajun．ActaMeiallSin,1990;3B:43d No related articles found!
