The decomposition reaction process of waste rare earth (RE) polishing powder was monitored in real time by the thermogravimetry–differential thermal analysis (TG–DTA) and Fourier transform infrared spectroscopy (FTIR). The results showed that the reaction was divided into two stages, and the thermal weight losses got to stable when the temperature was more than 400 °C. The releasing gas mainly contained H2O and SiF4, and the reaction kinetics during decomposition process was studied by the methods of Freeman-Carroll and Kissinger.
