Thermal properties of high-porosity monoliths based on exfoliated graphite

High-porosity monoliths with densities in the range 50 to 300 kg/m(3) have been prepared by uniaxial pressing of exfoliated graphite and their thermophysical properties have been investigated both along and across the pressing direction. We have determined strength characteristics of the monoliths: elastic modulus in compression and bending strength. The procedure used to prepare exfoliated graphite is shown to influence the physicomechanical properties of the monoliths.
