摘　　要：研究了氟铝酸钙（Ｃ１１Ａ７ＣａＦ２）和氯铝酸钙（Ｃ１１Ａ７ＣａＣｌ２）两种矿物在原材料经水热预处理的条件下，即在Ｃ３ＡＨ６－Ａｌ（ＯＨ）３－Ｃａ（ＯＨ２）－ＣａＸ２（ｘ＝Ｆ，Ｃｌ）系统中的形成规律，研究结果表明，原料经水热预处理以后，Ｃ１１Ａ７ＣａＸ２（ｘ＝Ｆ，Ｃｌ）的形成温度较ＣａＣＯ３－Ａｌ２Ｏ３－ＣａＸ２（Ｘ＝Ｆ，Ｃｌ）系统大大提前，而矿物的水化特性基本上没有区别。In the system of C3AH6-Al(OH)3-Ca(OH)2-CaX2(X=F,Cl), the formation law of C11A7·CaF2 and C11A7·CaCl2,which raw materials are pretreated under hydrothermal conditions,has been studied. It is shown that in the system of C3AH6-Al(OH)3-Ca(OH)2-CaX2 the temperature of producing C11A7·CaX2 is much lower than that of C11A7·CaX2 Produing in the system of CaCO3-Al2O3-CaX2,but hydrtaon properties of C11A7·CaX2 in two producing conditions have not different.
