Abstract: In this study, the effect of freeze casting method to fabricate thermal insulators is analyzed. Gelation freezing was done to create unique honeycomb-like microstructures with high porosity. A Hot Disk TPS 1500 was used to measure the thermal conductivity of the insulators with the transient plane source (TPS) method. Results showed that the insulators exhibited very low thermal conductivities.
