In this study, a series of SiC-Al₂O₃ ceramic foams (SACFs) were fabricated from the powders of commercial silicon carbide and fused white corundum by polymeric foam replication method combined with reaction sintering process. Effects of sintering temperature (1250 °C-1350 °C) and addition amounts of V₂O₅ (0–3 wt%) on the sintering properties and post-sintering properties of as-prepared SACFs such as appearances, microstructures, phase compositions, apparent porosity, bulk density, cold compressive strength and thermal shock resistance have been investigated. During the sintering process, SiC was oxidized in air and formed SiO₂, then part of as-formed SiO₂ reacted with Al₂O₃ to produce Al₆Si₂O₁₃ ceramic phase. The mechanical properties of as-prepared SACFs were found to be remarkably increased due to the increase of the sintering temperature and the introduction of V₂O₅. The phase …
