摘要：

The systems CaO-ZnO-Al2O3 (C-Z-A) and CaO-ZnO-Fe2O3 (C-Z-F) have been studied and their phase relationships established. Two hitherfo unreported phases, Ca3ZnAl4O10 (C(3)ZA(2)) and Ca6Zn3Al4O15 (C(6)Z(3)A(2)) were characterized in the system C-Z-A: their X ray diffraction patterns were obtained and indexed No new phases were discovered in the system C-Z-F. Phase coexistence has been established in both systems. C(6)Z(3)A(2) is of particular interest to clinkering because it coexists with alite, belite and a clinker liquid phase. This is confirmed both by laboratory experiment and its identification in white and grey clinkers, made from industrial raw meals doped with 10 and 20 wt% of zinc oxide.
