The Griineisen constant at 22.2 K is considerably lower than the room temperature value given in Table 3.7. 

Plausible elastic constants of cBN are listed in Table 5 by summing up the theoretically expected (10,94-96,124,140,141) and experimentally observed data (74,143-145). Griineisen parameters (143,144) and linear thermal expansion coefficients near room temperature (146,147) are also listed. The elastic constants of cBN are about 20-40% lower than those of diamond and several times larger than those of other covalent crystals such as Si and GaAs. Although cBN is stiff, it is elastic and can be distorted the volume of cBN decreases elastically by about 20% at 100 Gpa (Fig. 21) (74).
