The thermal properties, as well as bulk density, and mass loss of alumina porcelain were determined as a function of firing temperature. It was found that after sintering at 1320 ÂșC, the thermal conductivity and thermal diffusivity increased by ~700% and ~400%, respectively....
Using industrial grade mullite powder and a foaming and starch consolidation process, a series of porous mullite ceramics were prepared. These ceramics were analyzed by a thermal constants analyzer, and it was determined that the ceramics had low thermal conductivities and would make good thermal ...
