The physical properties, including thermal conductivity, pore structure, and tapped density, of a novel nanoporous silica material. Thermal conductivity was measured, which determined two values of 0.0284 and 0.0294 W/mK. The materials had a high porosity of 95-97%. The lowest density obtained was 0.077g/cm3. High resolution scanning microscopy and nitrogen physisorption were also used as part of the study....
