Porous materials have widespread industrial applications. In this study, mullite materials with porosities between 72-86 vol% were fabricated and a thermal analyzer (TPS) 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....
Researchers have developed an innovative processing route for producing microcellular cordierite ceramics within a three-step method. A) constructing ceramic-filled foams by heating a mixture of polysiloxane, expandable microspheres, talc, and alumina B) cross-linking the foamed body, and C) with the use of sintering, convert the body into microcellular cordierite ceramics....
