Abstract: Very porous ceramics were prepared by the direct foaming method containing 79% kaolinite , based on commercial clay. Ceramics were prepared with different pore volume fractions, and the different ceramics were analyzed using the transient plane source (TPS) technique to measure thermal conductivity. Increasing pore volume fraction led to decreased thermal conductivity.
