Stability aspects of the ionic‐covalent crystals are investigated in terms of the bond charge model. A definition of the covalent bond charge is proposed for the A‐ N B 8– N semiconductors with zinc‐blende structure. The possibility is discussed to use the bond charge as an order parameter to describe the transition from zinblende to NaCl type structures. The trends for the parameter change of the Keating‐Martin valence‐force‐field model with bond charge variations are investigated.
