Electrostatic surface potentials of selected calcite planes and their possible relationships to the morphology of this mineral

Surface potentials of ionic crystals are calculated. As an example, calcite is used because of the great variety in its form development. The surface potentials of 26 selected calcite planes are calculated according to the method of Madelung. The resulting order of magnitude of the potential is compared with the frequency of the occurrence of these faces on natural calcites.
