摘要：Influence of boron content in boron-based pyrotechnic composition and particle size distribution of oxidiser, i.e., KNO3 in boron-based pyrotechnic composition is examined by subjecting these to various tests. Study on boron-based pyrotechnic compositions reveals that compositions with 20, 25 and 30 parts by weight of boron are promising igniter compositions wrt their calorimetric values, pressure maximum, ignition delay, etc. However, from sensitivity point of view, the composition with 30 parts of boron is more safe to handle, manufacture and use. From the study of particle size distribution of KNO3 in Mg- based pyrotechnic compositions, it is observed that the composition with wider particle size distribution of oxidiser gives better packing density for their binary miJQ with metal fuel, which in turn gives lower ignition delay and ignition temperature.
