摘　　要：使用化学纯的试剂，研究了ＣａＯ、Ｈ２ＳｉＯ３和Ａｌ（ＯＨ）３系统中，当Ｃ∶Ｓ∶Ａ＝２∶１∶１时，Ｆ、Ｃｌ和ＳＯ３对Ｃ２ＡＳ形成过程的影响。结果表明在８５０～１０５０℃的温区内，ＣａＯ－Ａｌ（ＯＨ）３－Ｈ２ＳｉＯ３系统中Ｃ２ＡＳ的形成数量极少，主要矿物是Ｃ１２Ａ７，Ｃ２Ｓ和β－ＣＳ，当有Ｆ、Ｃｌ和ＳＯ３存在时，Ｃ２ＡＳ的数量大大增加，在１０５０℃时，Ｃ２ＡＳ的数量可达８０％左右。In this paper,the influence of existances of F,Cl and SO 3 on the formation of C 2AS is studied in CaO H 2SiO 3 Al(OH) 3 system at 2∶1∶1(C∶S∶A), where the agents are in chemical pure grade. The results show that, in the range of 850￣1050 ℃,a minute amount of C 2AS is formed in CaO H 2SiO 3 Al(OH) 3 system,and the main minerals formed are C 12 A 7,C 2S and β CS. However,the existances of F,Cl and SO 3 remarkably increase the amout of formed C 2AS, and the content of formed C 2AS can be as high as 80% at 1050 ℃.
