Show THERMAL DECOMPOSITION KINETICS OF AN ENERGETIC NICKEL COMPOUND Brad Warlick Chemistry Bradley Q. Warlick, (Dr. Charles Wight), Department of Chemistry, University of Utah The decomposition kinetics of Nickel(ll)-hydrazine-2,3-pyrazin- edicarboxylate 3H2O were characterized through the use of thermogravimetric analysis (TGA), as well as differential scanning calorimetry (DSC). These techniques were used to determine the compound's thermal stability and total energy release as a func-tion of both time and temperature. By conducting several series of experiments at different heating rates, we were able to extract robust values of the decomposition kinetic parameters with the use of an advanced isoconversional method. The analysis reveals that the initial steps in the compound's decomposition are due to a reversible dehydration. Based on an analysis of TGA values, the activation energy for the main exothermic step in the decom-position was found to be ~135 kJ/mol. DSC values confirmed this finding to within 7 percent. |
