简介
Ceramic foam are a class of high porosity materials that are used for a wide range of technological applications. In this study, ceramic foam was produced by polymeric sponge replication method. In this process, commercial polymeric foam was used as template and dipped into ceramic slurry followed by drying and sintering to yield a replica of the original polymeric foam. The study was focused on the fabrication of different density of ceramic foam by varying the density of ceramic slurries (1.1876, 1.2687, 1.3653 and 1.5295g/cm3). Physical properties of ceramic foam produced such as density was characterized according to ASTM C 271-94 whereas porosity was characterized using Archimedes method. Bending and compressive strengths were determined following the ASTM C1161-94 and C773-88 (1999), respectively. The morphological study was performed using scanning electron microscopy (SEM) and …
