Electrical Conductivity of Graphite Journal of the Physical Society of Theoretical calculations are given for the electrical conductivity of graphite in the hexagonal layer planes. The resistivity increases with temperatures as T 1.2 between 25K and 77K. In the long Graphite: Thermal and electrical conductivity Chemistry Stack 10 Aug 2018 You are wrong to say that graphite has free electrons. The electrons are bound to sheets of aromatic ringsdelocalized but not free. In electrical conduction, the electron pairs are able to jump from bond to bond on the sheet What is the thermal conductivity value of graphite in the xy planeThe thermal conductivity,like thermal expansion, is strongly influenced by the anisotropy of the graphite crystal. The perfect or the near perfect graphite crystal is believed to have the highest known thermal conductivity of any material and has
