Stabilization of metallic emulsions by in-situ precipitating intermetallic layers

Abstract

A new concept to stabilize liquid metallic emulsions by intermetallic layers, precipitated upon cooling has been developed. This new concept has been proven experimentally. Cadmium-rich droplets are dispersed in an aluminum-rich liquid matrix containing dissolved strontium. Upon cooling, phase Al 4Sr precipitated along the surface of the droplets. The Al 4Sr phase forms an "envelop" along the surface of the droplets, ensuring their stabilization against coalescence. © 2012 Elsevier Ltd. All rights reserved.
