Depending on the reaction chamber and throat material and conditions, it
might be possible to use ultrasonics to break the aluminum into fine
droplets.

Hmmm, I vaguely that there are ways to make ultrasonic "whistles".  I don't
know if this could be applied to the injection system, but if it could, it
would at least not require an electrical power source.  It does sound complex
though; hopefully existing injection technology will produce droplets of
sufficiently small size.

I wonder if acoustical energy can somehow be used to protect the surfaces
from accumulation of aluminum oxide?
