Claim:
1. A process for preparing material for tracer ammunition, comprising the operations of: receiving first particles of exothermic material of a first average size at a first ultrasonic processing station that includes an ultrasonic transducer; applying ultrasonic energy to the particles by the first ultrasonic processing station to break down the received particles of exothermic material into reduced-size particles of a second average size that is smaller than the first average size; transferring the reduced-size particles into one or more successive ultrasonic processing station, wherein at least one successive ultrasonic processing station applies ultrasonic energy to particles it receives to further reduce the average size of its received particles; and compacting a light producing material onto the exothermic material to form a tracer pellet.
