Progress

• Synthesized Al particles over range of
  conditions fromAlCl3 feed system in plasma torch
  apparatus
• Determined effects of reactant feed rates and of
  counterflow on particle-size distributions with
  scanning mobility particle sizer
• Characterized particles off-line by
• transmission electron midroscopy
• energy dispersive X-ray spectroscopy
• In progress
• thin oxide growth on Al nanoparticles
• passivation with polymer films
