What is the thermal conductivity of hollow glass microspheres
The conductivity was found to be 0.65–0.77 W/m·K, and the density was 0.4–0.46 g/cm3. Glass typically has a tensile strength of 7 megapascals (1,000 psi). However, the theoretical upper bound on its strength is orders of magnitude higher: 17 gigapasc...…
