In order to suitably initiate an impulse cartridge and to get the desired peak pressure, high energy igniter and booster pyrotechnic compositions may be required. Studies were undertaken to develop different types of high energy igniter and booster pyrotechnic compositions comprising B/KNO3, Zr/KClO4 and Pb(SCN)2/KClO3 as igniter compositions, and B/Mg/KClO4/Bi2O3 and B/Mg/KClO4 as booster compositions. Different ratios of fuels and oxidizers were studied in order to determine the best igniter and booster compositions. The measurement of the calorific values for the igniter and the booster compositions, along with safety tests of the igniter compositions, were performed. The pattern of calorific values observed for the igniter and booster compositions under study were B/KNO3 > Zr/KClO4 > Pb(SCN)2/KClO3 and B/Mg/KClO4 > B/Mg/KClO4/Bi2O3, respectively. The newly-developed high energy igniter compositions passed all of the safety tests. Both igniter and booster compositions were also subjected to functional tests in an impulse cartridge. The functional tests were intended for the determination of peak pressure and time to peak pressure. These high energy igniter and booster compositions increased the peak pressure by 8.3% and reduced the time to peak pressure by 14.3% for an impulse cartridge in a closed chamber of volume 230 cm3. The consequence of this research work is that the best combination of igniter and booster compositions in terms of safety, calorific values and cartridge functionality are Zr/KClO4 (40/60) and B/Mg/KClO4 (30/10/60), respectively.
