Dust is dust, other than element and effects generated they will behave in a fundamentally similar manner.

And of course ani gravity vehicles will fail quickly if their fuel all gets burned up; so would an air plane.

C-4 is stable enough to use as bricks in a fire pit, but giving it aa good jolt is still going to set it off; dust seems to, in-universe aura is specifically stated to activate dust. The energy surge when his aura was active instantly healed the wounds he had, and he visibly glowed for a few seconds. If that wasn't enough energy to activate something like what you are suggesting, he will never be able to do so.

More importantly what you are describing (microscopic dust crystals) is ''literally powder. ''So making a distinction between the stability of powder vs crystals is irrelevant.
