S. P. Sivapirakasam and M. Surianarayanan* Abstract: Firework chemical mixtures are sensitive to thermal and mechanical stimuli and lead to many explosive incidents. Experimentally determined thermal and mechanical (impact and friction) sensitivity data of a flash composition mixture are subjected to statistical and graphical analysis in order to understand the mechanism of triggering accidents. The …

Effect of Particle Size on the Mechanical Sensitivity and Thermal Stability aspects of Pyrotechnic Flash Compositions
S. P. Sivapirakasam, M. Surianarayanan,* F. Chandrasekaran and G. Swaminathan Abstract: The mechanical and thermal sensitivity of pyrotechnic flash compositions consisting of mixtures of potassium nitrate (KNO3), sulphur (S) and aluminum (Al) with varying particle sizes of KNO3 and Al indicated that, irrespective of the composition of the cracker mixture, all the compositions were found …
