Abstract: Using a gelation-freezing method, diatomite-derived porous silica ceramics with high porosities up to 90% were fabricated. Diatomite particles contain large numbers of meso- and micropores, intrinsically reducing the thermal conductivity. In this study, thermal conductivity of the sintered specimens was measured using the Hot Disk TPS1500 method with transient plane source. Results indicate that ceramics had a low thermal conductivity due to their very high porosity.
