Abstract: Porous materials have widespread industrial applications. In this study, mullite materials with porosities between 72-86 vol% were fabricated and a hot-disk thermal analyzer (TPS2500s) measured their thermal conductivity using the transient plane source (TPS) technique. Results showed that as the porosity of the mullite materials decreased, thermal conductivity increased.
