EFFECTS OF PARTICLE-SIZE MORPHOLOGY ON ULTRASONIC-INDUCED CAVITATIONAL MECHANISMS IN HETEROGENEOUS SYSTEMS

Ultrasonic irradiation of copper and lead, separately, in hydrochloric acid shows that mechanistic effects would depend largely on the struc tural nature of the solid reactants: if the size of a solid reactant i s substantially large, microject formation will be the predominant mec hanism.
