Ultrasonic propagation through aqueous kaolin suspensions during degassing

Austin, James C.; Challis, Richard E.

Abstract

A degassing procedure is necessary prior to taking ultrasonic measurements in aqueous kaolin suspensions as well as many other liquid based colloids. In this work we compare two degassing methods and show that subjecting a sample to a power ultrasound field is easier and less time consuming than exposing it to a vacuum. We also combine degassing and deflocculation procedures to show that air bubbles are trapped in cage-like kaolin flocs and are released when such flocs break up.
