| Abstract: | The specific heat at constant pressure and the velocity of sound in the SiC/Si biomorphic composite prepared from white eucalyptus wood are measured in the range 3.5–65 K and at 77 K, respectively. The heat capacity of the SiC/Si sample under investigation is calculated within three proposed models according to the Kopp-Neumann additivity rule. |
