The acoustic and thermal properties of graphite are highly anisotropic, since phonons propagate quickly along the tightly bound planes, but are slower to travel from one plane to another. Graphite's high thermal stability and electrical and thermal conductivity facilitate its widespread use as electrodes and refractories in high temperature material processing applications.

2013/1/1Etter et al. reported that aluminum and graphite interface may form needle-like Al 4 C 3 phase at aluminum–graphite interface via liquid infiltration process. The Al 4 C 3 phase is brittle and tends to absorb moisture which degrades both the mechanical properties and thermal conductivity of

Thermal properties of graphite

The interatomic spacing between the carbon atoms of graphite is a function of temperature. At 0 K, these atoms have their lowest energy position or ground state. The increased energy resulting from increasing temperature causes the atoms to vibrate and move further apart. In other words, the mean interatomic spacing increases and the result is thermal expansion. This can be represented

Thermal properties of molded graphite

Thermal conductivity: The thermal conductivity of the ideal graphite crystal was reviewed in Ch.3, sec. 4.3. The mechanism of heat transfer is by lattice vibration and the thermal conductivity is approximately 200 times greater in the basal plane than across the planes, thus reflecting the anisotropy of the graphite crystal. This anisotropy is less pronounced in molded graphite
