本文报道了在950 °-1150 °C温度范围内对CaO-Al2O3-SiO2-SO3体系富CaO部分的实验研究。发现了6个四相和18个三相相，它们确定了CaO，Ca_2SiO_4，Ca_3A_2O_6，Ca_（12）A_（14）O_（33），Ca_4A_2O_4，硅硫酸钙（Ca_5Si_2（SO_4）O_8）和铝硫酸盐（Ca_4A_2O_6（SO_4）O_（12））之间的平衡。在1175 °以上，Ca_3SiO_5趋于稳定。可能偏离平衡过程中熟料进行了讨论。
Experimental studies are reported on the CaO-rich portions of the system CaO-Aℓ2O3-SiO2-SO3in the temperature range 950°–1150°C. Six four-phase and 18 three-phase essemblages have been found. These define the equilibria between CaO, Ca2SiO4, Ca3Aℓ2O6, Ca12Aℓ14O33, CaAℓ2O4, calcium silicosulphate (Ca5Si2(SO4)O8) and aluminosulphate, Ca4Aℓ6(SO4)O12. The equilibria above 1175°, where Ca3SiO5becomes stable, are predicted. Possible departures from equilibrium during clinkering are discussed.
