Abstract:

The goal of this report is to summarize the experimental results and studies of aluminum combustion in sulfur hexafluoride atmosphere. The particles has been ejected from exploding wire. Using photography, burning time, particle size, velocity, deceleration, and temperature were measured. Typical results are as follows 380 or - 25 micron diameter particles burn in 10 or - .75 ms the average initial velocities were from 10 ms to 15 ms the average decelerations were from 4000 msq s to 8000 msq s. The average temperature of the burning particle was 2750 or - 150 K. According to the burning studies of the particles and the measured temperature results the mechanism of burning can be surface burning or vapor phase burning that occurs close to the surface of the hot particle.
