Experimental analysis on nano scale flash powder in cake bomb fire crackers

Abstract

Firework products are a type of pyrotechnic device used for newlineentertainment Firework products are of two types namely light producing and newlinenoisesound producing Fireworks are made of an oxidizer ignitor fuel and newlineoptionally a colour enhancing chemical and a binder The selection of newlineoxidizer and fuel has the potential for having a major influence on the newlineefficiency of the pyrotechnic mixture The chemicals employed and their newlinecompositions vary depending on the type of fireworks being produced Flash newlinepowder is one of the compositions being used in sound emitting firework newlineproducts like cake bomb chinese crackers etc The flash powder composition newlineconsists of Potassium Nitrate KNO3 SulphurS and AluminiumAl which newlineare having the particle size of approximately 75 m The performance of the newlinefirecrackers is mainly governed by the level of noise when bursting newline newline
