Various dislocation configurations are examined in the fluorite structure for the presence of long‐range electrostatic charge assuming slip systems of the {001} 〈110〉 type. It is concluded that neither pure edge or screw dislocations nor jogs and kinks on edge or screw dislocations need necessarily give rise to long‐range charge, although adsorption or desorption of anions and cations could give rise to such charge. Based on these results and existing experimental data, facility of dislocation glide and likelihood of charge transport by dislocations are assessed.
