Alumina and Alumina/Zirconia Multilayer Composites Obtained by Slip Casting

Abstract

The slip casting technique has been revealed as a powerful method to obtain multilayer composites close to theoretical density. From zeta potential and viscosity measurements of Al 2 O 3 and Al 2 O 3 /ZrO 2 (4 vol% ZrO 2 ) suspensions, the corditions for the preparation of multilayer composites by slip casting have been determined. A microstructural analysis of the different layers by scanning electron microscopy is also reported.
