Thermal conductivity of porous materials

To obtain thermal conductivity less than 0.1 W/m/K, it is necessary to select a solid phase with an intrinsic thermal conductivity of 1 W/m/K or less combined with a pore volume fraction 90%. This is demonstrated by differences observed in measurements for kaolin-based foams, calcium aluminate foams, and silica aerogels.
