The abnormal ablation of insulation materials caused by slag deposition in solid rocket motors has gradually attracted considerable attention from researchers. First, an alumina-charred layer system was thermogravimetrically experimented with 1700–1850 °C using ultra-high-temperature thermogravimetric equipment based on the dominant equation of an Al 2 O 3 –C system obtained from previous studies. The kinetic parameters of the alumina-charred layer reaction system were then determined by the isothermal kinetic mathematical treatment method. Second, an ablation model was established to verify the accuracy of the kinetic parameters. The ablation thickness calculated by the model is nearly similar to that in the experimental results, with an error of 16.01%. Results show that the kinetic parameters of the alumina-charred layer's reaction system obtained in this study are credible and can be used for predicting the insulator's ablation under deposition conditions.
