| description | The prediction of equilibrium components for chemical reactions is a considerable section in the metallurgical industry. According to the ion and molecule coexistence theory (IMCT), a modified mass action concentration model based on a thermodynamic database is proposed in this paper, which complys with the law of mass conservation and can be applied in the batching process for Al-Ti-Ca-oxide system that originates from SHS (Self-propagating High-temperature Synthesis) metallurgy. The trend for slag and alloy component under different batching conditions are in good agreement with experiment, while the difference between the theoretical calculation and experiment can be attributed to the deviation from the thermodynamic equilibrium. The modified mass action concentration model with melts and slag can be used to predict the composition and content of the system when equilibrium is achieved at a certain temperature under a specific material ratio, which is conducive to reducing the cost of the experiment and predicting the operability of the actual process. Moreover, it is believed that this thermodynamic insight may has certain application prospects in these metallurgical procedure based on the equilibrium process. |
