Role of Silicon in Boron Potassium Nitrate System.
Keywords: Burning rate, Pyrotechnic ignition system
AbstractTo examine the possibility of improving the ignition characteristics of the commonly used pyrotechnic ignition system based on B-KNO/sub -Binder (30:70:10), B was gradually replaced by Si in its composition. The addition of Si was found to reduce the maximum pressure find increase the ignition delay. Maximum dp/dr value was observed with the composition containing 5 per cent Si. The differential thermal analysis results showed single sharp peaks for ignition in the temperature range 500-570 degreeC. The heat of combustion and burning rate decreased with increase in Si content. Impact sensitivity of the compositions increased with increase in the percentage of Si, whereas no change was observed in the friction sensitivity in comparison with the base composition.
