A Study of Thermal Decomposition and Kinetic Evaluation of Boron Blended Flash Powder CompositionSource: Journal of Thermal Science and Engineering Applications:;2021:;volume( 014 ):;issue: 007::page 71009-1DOI: 10.1115/1.4052691Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Herein, the thermal characteristics of flash powders of different combinations of potassium nitrate, sulfur, aluminum, and boron are reported. From the literature, it is identified that boron implements lack of sensitiveness to flash powder mixture, which promotes safety during the manufacturing process. But the thermal behavior of the boron blended compositions remains a mystery. Hence, various combinations of flash powder compositions are prepared by keeping the % of KNO3 and % of S constant, and gradually 23% of aluminum is reduced (23% to 0) by increasing the quantity of boron (0% to 23%) in 19 trials and are subjected to thermogravimetric analysis (TGA)/differential scanning calorimetric (DSC) analysis individually. The TGA and the DSC analysis reveals that the 65.65% replacement of aluminum with boron mixture shows predominant characteristics which is suitable for fireworks. Also, the reaction kinetics and the critical ignition temperature are calculated for the optimum composition. The performance of the fireworks product is checked with varying quantities to meet out the optimum quality.
