calculation model for slag system of CaO-Cu2O-Fe2O3 WANG Jin-liang1, 2, ZHANG Chuan-fu1, ZHANG Wen-hai1, 3 (1. School of Metallurgical Science and Engineering, Central South University, Changsha...) Abstract: According to the coexistence theory of slag structure, the activity calculation model for slag system of CaO-Cu2O-Fe2O3 was built from 1 200 ℃ to 1 300 ℃. Then, the activities of CaO, Cu2O......

method and the related thermodynamic data were obtained. The results show that AlF3 is obtained after three-step decomposition reaction of (NH4)3AlF6, and the solid products of the first two... temperatures were calculated. Enthalpy and entropy changes of the three reactions were analyzed by DSC method. Anhydrous aluminum fluoride was prepared. The XRD analysis and mass loss calculation show......
