Abstract

Rheological behaviour of Al2O3 and CuO suspensions was characterised in order to fabricate Al2O3/Cu foams as an alternative way to produce foams with better mechanical properties than common Al2O3 foams. Different quantities of raw materials were combined to select the formulations for the ceramic-metal foams. Foams were produced by a double impregnation process, followed by a thermal cycle and a reduction cycle. In this work, materials were characterised trough zeta potential, SEM and optical dilatometry. Foams microstructure and compressive strength were evaluated. Final structures had a compressive resistance of 0.44 ± 0.14 MPa.
