Ceramic foam is a class of highly porous materials that are used for wide range of technological applications, specifically as absorbents and membrane for wastewater treatment process. Among the potential materials include silicon carbide (SiC), alumina (Al2O3), zirconia (ZrO2), titania (TiO2), and silica (SiO2). The review clarifies on the broad types of ceramic foam, and the common techniques of foam fabrication, such as polymeric sponge method, starch consolidation, direct foaming, and gel-casting of foam. The parameters of each fabrication techniques will be discussed crucial based on the new research findings in the field of ceramic foam.
