摘　　要：以正硅酸乙酯 (TEOS)和 Ca(NO3 ) 2 · 4 H2 O为前驱物用溶胶 -凝胶法制备单矿物C2 S粉末。用甘油乙醇法测定 C2 S粉末的游离 Ca O含量 ;用 X射线衍射、红外光谱分析探讨了加水量、溶剂种类以及热处理制度等工艺参数对 C2 S粉末形成的影响 ;用扫描电镜观察水化 2天的 C2 S粉末以证实其活性。This paper discusses C_2S powders prepared from tetrathoxysilane(TEOS) and Ca(NO_3)_2·4H_2O with solgel method. CaO is determined by glycerinealcohol method; XRD and IR are used to analyze the effect of progressing parameters, such as water content, the type of solvents and heating system, on the C_2S powders. To confirm its activity, SEM is used to observe the C_2S paste which has hydrated for two days.
