Thermal conductivity and characterization of compacted, granular silica aerogel

•Compaction decreases the conductivity of aerogels from 24 to 13mW/(mK).•13mW/(mK) is comparable to values for monolithic silica aerogels.•There is an optimum level of compaction to minimize thermal conductivity. Monolithic silica aerogels are well known for their low thermal conductivity (approxima...
