摘要
Experimental studies are reported on the CaO-rich portions of the system CaO-Aℓ2O3-SiO2-SO3 in 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 Ca3SiO5 becomes stable, are predicted. Possible departures from equilibrium during clinkering are discussed. © 1979.
