The rich diversity of compositions, structures and properties of metallic alloys has led to their widespread applications in the fields of electronics and catalysis. Surface structures, composition and segregation properties of bimetallic nano crystals (BMNs) are of interest as they are important in determining chemical reactivity, especially catalytic activity. Moreover, bimetals are also of interest as they may display structures and properties which are distinct from those of bulk bimetals. Burning rate of solid propellants is an important parameter because it is directly related to the performance of the propellant. The catalytic thermal decomposition of ammonium perchlorate (AP) and burning rate of composite solid propellants (CSPs) are remarkably sensitive to additives. In the present work, BMNs have been synthesized, characterized and their catalytic effect on the thermal decomposition of AP has been evaluated. Further, these were found to enhance the burning rate of CSPs.
