Thermal properties of graphite- thermal conductivity ...

The thermal properties of conductivity and expansion are strongly influenced by the anisotropy of the graphite crystal. The thermal conductivity (K) is the time rate of transfer of heat by conduction. In graphite, it occurs essentially by lattice vibration and is represented by the following relationship: Eq (1) K=bCpvL Where b= a constant C= specific heat per unit volume of the crystal v ...
