The behavior of soot particles was investigated under the microgravity condition using a 490 m (10 second microgravity duration) drop shaft. A butane jet diffusion flame was formed above a burner tube with 6 mm inner diameter. The fuel velocity and the oxygen concentration of surroundings were varied. Generated carbon particles were sampled and their detailed structures were observed using the electron microscope. The results showed that characteristic soot clusters were formed in the flames under microgravity. It was found that the generated soot particles in the flames under microgravity were agglomerated and grew to about 200-500 times as large as one generated under normal gravity.
