A technique for the preparation of NiO-YSZ cellular ceramics is presented. The technique is based on the in-situ polymerization of a Polyurethane system loaded with the ceramic powders. After sintering, materials with a total porosity value as large as 70% can be obtained, showing a bimodal distribution of the porosity, related to the open cell structure and the porosity of the scaffold network. In fact, the walls of the foam were not fully densified, permitting obtaining a microstructure with a very large triple phase boundary (TPB).

Abstract

A technique for the preparation of NiO-YSZ cellular ceramics is presented. The technique is based on the in-situ polymerization of a Polyurethane system loaded with the ceramic powders. After sintering, materials with a total porosity value as large as 70% can be obtained, showing a bimodal distribution of the porosity, related to the open cell structure and the porosity of the scaffold network. In fact, the walls of the foam were not fully densified, permitting obtaining a microstructure with a very large triple phase boundary (TPB).
