摘要
本文评述了文献申报道的有关无水硫铝酸钙(4CaO·3Al_2O_3·SO_3,简写为C_4A_3S)的晶体结构研究,包括已获得的成果和存在的问题。这些研究工作虽然对C_4A_3S进行了粉末和单晶X射线分析.但到目前为止只测定出C_4A_3S空间群为I43m的亚晶胞(α_0=9.167A),它的晶体结构问题尚未最终解决.
In this paper, a review of the literature has been given, which reports the results obtained and the questions presented in the study of anhydrous calcium aluminosulphate (C_4A_3S) crystal structure. Although X-ray analysis was made for powder and single crystal of C_4A_3S, to date only the structure of the subcell (a_0= 9.167 A) with space group I43m has been determined. The problem of its crystal structure has not been finally solved yet.
