Abstract

Experimental results are presented on the effective thermal conductivity of rocks (sandstone and granite) and polycrystalline arsenic chalcogenides. Measurements are made using an absolute steady-state approach in the temperature range of 273–523 K and at hydrostatic pressures of up to 400 MPa. A power-law temperature dependence of thermal conductivity with a negative exponent is specific to the investigated samples at a fixed pressure. A description of this dependence is proposed. The values used in the equation are calculated from the experimental data.
