Energy of some stacking faults were evaluated in ionic compounds of the NaCl and CsCl type. One obtains in the NaCl structure energies varying from 240mJ/m2 for the (111) faults of LiF to 20mJ/m2 for KI. The dissociation of dislocations then deduced were low except possibly for NaCl and KI where one obtains 2 to 3 interatomic distances. In the case of CsCl, CsBr and CsI one obtains (110) stacking fault energies of the order of 200 to 300mJ/m2. Thus CsI stacking fault's energy was near the critical value necessary to the metallic glide in the [111] direction as observed in more metallic compounds such as Ag-Mg.
