Abstract

The thermal decomposition of 3‐nitro‐1, 2, 4‐triazol‐5‐one magnesium complex and its kinetics were studied under the non‐isothermal condition by DSC and TG/DTG methods. The kinetic parameters were obtained from analysis of the DSC and TG/DTG curves by the Kissinger method, the Ozawa method, the differential method and the integral method. The most probable mechanism functions for the thermal decomposition of the first stage, the second stage and the third stage were suggested by comparing the kinetic parameters. The entropy of activation (Δ__S__^−^), enthalpy of activation (Δ__H__^−^) and free energy of activation (AC) at Tpdo are‐66.74 J‐mol^−1^K^−1^, 119.2 kJ‐moI^−1^ and 152.44 kJ · mol^−1^, respectively.
