  • Amorphous boron powder (ABP) has a comparative edge over conventional fuels like aluminum, magnesium, etc., owing to its high heat of combustion for use in fuel-rich propellants for integrated rocket ramjets. The low atomic weight, high heat output, ready ignitability with KNO, releasing large amounts of heat, and persistent burning even at low-pressure2 make boron-based pyrotechnic composition a beautiful igniter.
