摘要
本文借助XRD、XPS、SEM/EDAX和化学分析等测试方法,对以石膏和莹石为矿化剂的C_3S-CaF_2,C_3S-CaSO_4,C_3S-CaF_2-CaSO_4、Alite-CaF_2、Alite-CaSO_4和Alite-CaF_2-CaSO_4系统的含(?),含(?)与含(?)和(?)的C_3S或Alite进行了结晶化学研究。得到(?)和(?)在C_3S或Alite中的固溶取代形式和极限固溶量,以及由固溶而引起的晶体缺陷和晶型转变规律。同时观察到含(?)和(?)的C_3S的超结构现象和含F的Alite的着色现象。
Adding gypsum and fluorite as mineralizer, the crystal structure of C_3S or Alite containing (?) and (?) in C_3S-CaF_2, C_3S-CaSO_4, C_3S-CaF_2-CaSO_4, Alite-CaF_2, Alite-CaSO_4 and Alite-CaF_2-CaSO_4 systems were studied by XRD, XPS, SEM/EDAX and chemical analysis. The types of substitution and the limits of solubility of (?) and in C_3S or Alite were obtained. The crystal defects and the stabilization of high temperature modifications due to the incorporation of (?) and (?) into C_3S or Alite were found. The superstructure of C_3S containing (?) and (?) aud the coloring phenomenon of Alike containing F were observed.
