Abstract

Today's diagnostic ultrasound technologies use sounds at low power and very high frequencies, in the MHz range. These sound waves have no permanent effect on the physical or chemical character of the material being examined. This new technology has become known as sonochemistry. Sonochemistry effects changes in materials as a result of cavitation, which is induced by the powerful ultrasound waves. Some main areas of investigation include: crystallization processes in metallurgy and pharmaceutical production; polymer technology; pigment dispersion and dyeing; preparation of nanosized powders; and electro-deposition and surface coatings.
