Development of Electroacoustic Methods and Their Application in Ceramic Processing



Vincent A. Hackley


The development of particle characterization methods based on electroacoustic effects is reviewed and their application in various areas of ceramic powder processing is stressed. Electroacoustics is a term used to describe the coupling between electric and acoustic fields in a suspension of charged particles (or ions). The colloid vibration potential (cvp) and electrokinetic sonic amplitude (ESA) are reciprocal effects, and can be used to measure particle charge and size in concentrated industrial suspensions where conventional techniques generally do not work. Commercial instruments for measuring ESA and CVP have been available since the late 1980's, and have reach a substantial level of technical sophistication only in the past four years. The current focus in electroacoustic instrument development is in the area of on-line measurements for industrial applications.
