| Abstract: |
| Through the thermodynamics analysis on CaO-Al2O3, CaO-Al2O3-SiO2, CaO-SiO2 and Al2O3-SiO2 system, the reaction laws were discussed during low calcium lime sintering process for bauxite. The results show that the generating reaction of CaO?Al2O3 and 2CaO?Al2O3?SiO2 occurs in sintering temperature range (1 200~1 400 ℃), Al2O3 and SiO2 can generate Al2O3?SiO2. |
