work is necessary in this field. More experimental evidence would be equally useful, particulary concerning carbon blacks, for which the graphitic structure may also be considered as nearly twodimensional. Such studies are under way in our laboratory.
The electrical conductivity of polycrystalline magnesite (MgCO 3 ) was measured at 3-6 GPa at high temperatures using complex impedance spectroscopy in a multi-anvil high-pressure apparatus. The electrical conductivity increased with increasing pressure. The activation enthalpy calculated in the tem
