Abstract
The d.c. electrical resistivity of coal-tar pitch has been measured from ambient temperature to 450 °C. The change in resistivity with temperature up to 200 °C has been found to be consistent with viscosity-controlled diffusion of current carriers. In an isothermal study at 450 °C, the start of mesophase formation was found to be accompanied by a rapid rise in the pitch resistivity, which subsequently levelled off and remained nearly constant until the onset of mesophase coalescence and phase inversion. The resistivity of the resultant mesophase pitch was found to be less temperature susceptible than that of the parent pitch.
