摘要：

A study was conducted on the reaction process between Fe2O3 and liquid aluminium by intentionally slowing down the reaction process. The reaction sequences during the thermite process were analyzed by using DTA. The phases and compositions of the reaction products were identified using electron microscopy and X-ray diffraction techniques. Based on experimental results and thermodynamic analysis, the reaction mechanisms of the thermite process were proposed.
