Abstract

The burn rates and ignition and flame temperatures of compressed Al/MoO 3 pellets were measured. The composites are composed of nano-scale reactant particles mixed and pressed to 52% theoretical maximum density. Experiments were performed by initially pre-heating samples to a uniform elevated temperature ranging from 20 to 200°C. Additional experiments were performed on samples initially at ambient conditions and with varied laser powers ranging from 10 to 60 W. Results allow comparison of combustion behaviors associated with nano- vs. micron-scale particle composites. The nano-scale particle composites are extremely sensitive to ignition when initially preheated. Burn rates for the compressed nano-composites were found to double when compared to the micron-scale composites.
