Description
Summary:The thermophysical and mechanical properties of compacted expanded graphite (EG) were studied. The experimental results were interpreted with application of similarity theory. The compacted EG critical density corresponding to the observed jump in the thermal conductivity coefficient and elasticity modulus was shown to depend on the expandable graphite preparation method, EG bulk density, and dispersion degree and amounted to 0.01 and 0.005 g/cm 3 for the studied EGs.
