The preferred form of solid state matter in the universe appears to be powder.  Earth's surface is covered with it, as is every rocky body we've checked (including our moon, Mars, and every asteroid). Some of the most beautiful astronomic structures we've observed across the universe are clouds of dust.  And for chemical reactions, small particles are more efficient. But the accustomed means of industrially dealing with particulates on Earth don't translate well to space. Sedimentation is out. Air handling is out.  Conveyor belts and gravity fed hoppers are out.

While others complain about the dust, Lunexus is building a suite of technologies leveraging that particular glory!
