ABSTRACT:
A ultrasonic cleaning system includes a tank composed of quartz or silicon carbide and one or more sleeved ultrasonic transducers mounted to the tank. The sleeved ultrasonic transducer has a two-part head mass, including a threaded sleeve and an outer housing that are composed of different materials. The threaded sleeve is preferably a metal that provides superior thread strength for mating with a compression bolt, while the outer housing is preferably silicon carbide or other ceramic material that provides a good thermal expansion match to the tank to facilitate adhesive bonding of the transducer to the tank.
