This article discusses the creation of a porous mullite ceramic through the incorporation of fly ash cenospheres (FAC) into mullite powder through the gelcasting process. Sintering temperature and the amount of FAC added were investigated as factors affecting density and strength. The authors found that the porous mullite ceramics had a high strength, and high porosity (48.1-72.2%) Thermal conductivity was measured and was determined to be 0.16-0.22 W/mK....
A series of compacted Bi0.5Sb1.5Te3 nanoplatelets are synthesized using hydrothermal methods, followed by cold pressing and sintering at temperatures between 300°C and 380°C. A variety of thermal, mechanical and electrical analyses are then performed on the synthesized nanoplatelets including: TPS technique for thermal conductivity, SEM/TEM/AFM to elucidate the mechanical and physical properties of the nanoplatelets, and the Oxford closed cycle cooler cryostat for measurement of electrical ...
Five different glasses were created in the present study with varying compositional ratios in a CaO-B2O2-SiO2 (CBS) System and the thermal and dielectric properties of these glasses were studied. A glass was found that had high thermal conductivity and promising dielectric properties, with a low sintering temperature that allows for the addition of fillers to adjust thermal and dielectric properties further....
