Decomposition Kinetics of Pyrotechnic Mixture from Sound-Producing Fire Crackers

A. Jeya Rajendran, T. Lekshmana Thanulingam, A. Meisudar and U. Manikandan Abstract: Dynamic, non-isothermal analysis of the pyrotechnic mixture of a sound-producing fire cracker, KNO3/Al/S/H3BO3,was carried out under N2 atmosphere by using a simultaneous thermogravimetric and differential thermal analyser. Intermediates and the residue formed in each stage of thermal decomposition of the pyrotechnic mixture were …
