Abstract: In this study, ultralow density silica aerogels were synthesized and their thermal conductivities were tested to determine how supercritical drying affected the samples. A Hot-Disk TPS2500 measured the thermal conductivity of the silica aerogels using the transient plane source (TPS) method which determined that the thermal conductivity of silica aerogels increased with temperature.
