The oxidation kinetics of AlN powder in CO2 atmosphere was investigated using thermogravimetric analysis. The experiments were carried out in the isothermal mode at different flow rates of CO2, 20 mL/min, 40 mL/min, 150 mL/min, and 265 mL/min. The results showed that the oxidation rate was affected by temperature as well as the flow rate of CO2. Based on the experimental data, a kinetic model for predicting the oxidation behavior of AlN powder has been developed, which could simulate both the chemical reaction and diffusion -controlling periods as a function of temperature and carbon dioxide concentration.
