The effective thermal conductivity of a porous material is due to both conduction and radiation processes.

Thermal conductivity of very porous kaolin based ceramics.

Porous ceramics were prepared by different methods to achieve pore volume fractions from 4 to 95. Very porous ceramics based on a commercial clay containing 79 kaolinite were made by a direct foaming method using methylcellulose drying at 70 c before a consolidation at 1100 c. Hence developing low cost porous mullite ceramics with high mechanical performance low thermal conductivity and good dielectric properties is very important for radome applications. Candidate materials for thermal insulation combine a solid phase of low thermal conductivity with porosity.

Candidate materials for thermal insulation combine a solid phase of low thermal conductivity with porosity. A theory is presented relating the effective conductivity to the conductivity of the solid material to the emissivity of the surface of the pores and to the size shape and distribution of the pores. In this paper a series of high porosity mullite ceramics with overlapped rod like grains were prepared from kaolin as extremely low cost raw material and. 16 however the overall or effective thermal.
