摘要：

We present the results of our experimental studies of the thermal conductivity for SiC and SiC + 1.2% BeO ceramic samples as a function of the hydrostatic pressure up to 400 MPa in the temperature range 273-523 K. We show that pressure leads to a nonlinear increase in thermal conductivity and to an additional phonon scattering by lattice defects. © Allerton Press, Inc. 2007.
