Material properties of diamond - Wikipedia
Because diamond has such high thermal conductance it is already used in semiconductor manufacture to prevent silicon and other semiconducting materials from overheating. At lower temperatures conductivity becomes even better, and reaches 41000 W/(m·K) at 104 K ( 12 C-enriched diamond).

The current understanding on the diamond machining of …
2014/5/20· Both diamond (the hardest naturally-occurring material identified to date) and silicon carbide are classified as hard and brittle [] due to their sp 3-bonded nature and shorter bond length. Under aient conditions, nitrogen is gaseous with only diatomic covalent bonds while boron, silicon and diamond (carbon) naturally form three-dimensionally covalent solids [ 2 ].

Atomistic aspects of ductile responses of cubic silicon …
Figure Figure4 4 also represents the chip morphology of β-silicon carbide (cubic) during the nanometric cutting process against a deformable diamond tool. It can be seen from Figure Figure4 4 that the cutting chips are curly shaped, which suggests that material removal is occurring in ductile regime by deformation rather than fracture.
