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 thermal analyzer 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....
This study analyses a mullite ceramic formed through foaming and starch consolidation of mullite powder, and how its thermal conductivity changes with porosity of the ceramic. The thermal conductivity was measured through the transient plane source (TPS) method with the TPS. As the porosity of the mullite ceramic increases so does the thermal conductivity....
