    Graphite is an electrical conductor, hence useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.

    The apparent electrical conductivity of a dry RVG 4000 [ Le Carbone Lorraine] graphite felt was measured in air using the very simple set-up of Figure 1. The thickness , initially 1.2cm, was modified by loading the upper copper disc with different loads (up to 8kg). A d.c. electrical power supply served to measure V-I plots,

    The electrical resistivity is an important parameter for graphite when used for the construction of heating elements. Fig2.26 shows the effect of temperature on a typical electrode material, whilst Fig2.27 shows the effect of the type of graphite and direction of grain on the electrical resistivity.

    Thermodynamically, graphite at atmospheric pressure is the more stable form of carbon. Diamond is trans-formed to graphite above 1500°C (Figure 1-4). The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms. The ideal graphite structure is shown in Figure 1-5.
