Abstract
Graphite serves as a key material for heat dissipation in electronic devices and nuclear engineering due to its remarkable thermal properties. The thermal expansion and conductivity of graphite have always been major scientific parameters in the field of carbon materials. Therefore, theoretical and experimental research in this area has received extensive attention. Research progress on the thermal expansion coefficient and thermal conductivity of graphite crystals is reviewed. Theoretical and experiment results on the thermal expansion coefficient of graphite are first introduced, followed by a discussion of the methods for measuring graphite thermal conductivity and the special phonon scattering mechanism in graphite. Finally, the uses of graphite in thermal management are summarized, and the development prospects in this field are discussed.
