The thermal decomposition of the magnesium oxalate dihydrate in a static air atmosphere was investigated by TG‐DTG techniques. The intermediate and residue of each decomposition were identified from their TG curve. The kinetic triplet, the activation energy E , the pre‐exponential factor A and the mechanism functions f ( α ) were obtained from analysis of the TG‐DTG curves of thermal decomposition of the first stage and the second stage by the Popescu method and the Flynn‐Wall‐Ozawa method.
