The Role of Boron in Thermal Decomposition of Ammonium Perchlorate

Abstract

<em>Simultaneous thermal analysis (STA) method has been applied to study decomposition reactions of AP under a flowing nitrogen atmosphere and static air. Results obtained indicate that a phase transformation occurs prior to the decomposition reaction. Decomposition takes place exothermally in two stages, first stage of decomposition could be suppressed by the controlled heating programme. Addition of a small amount of born lowered the temperature of the exotherm and increased the overall enthalpy of reactions.</em>
