Structure of the Crystalline Interface

Another example of dominant solvation effects is observed in the growth kinetics of the 100 faces of KI, KBr, and KCl crystals grown from aqueous solution. The desolvation energies of the anionic species of the potassium halide crystals increase in the order Cl Br I . Consequently, crystals composed of easily desolvated species are expected to grow fastest. In accordance with this hypothesis, the growth rates of the 100 faces of potassium halide crystals are found to decrease in the order KI KBr KCl (Bliznakov et al. 1971). 

Flat surfaces, or terraces, which are atomically smooth. 

Kink sites formed from incomplete regions on steps. 

Kossel hypothesized that kink sites present the most probable position for solute integration due to the higher bonding energy
