Abstract
The growth kinetics and elementary growth processes on the surface of NH4Cl:Mn2+ heterogeneous crystals formed in the NH4Cl-MnCl2-H2O-CONH3 system are experimentally studied. It is found that a change in the composition of complexes in an NH4Cl crystal from Mn(NH4)2Cl4 · 2H2O to MnCl2 · 2CONH3 leads to the occurrence of a local maximum in the kinetic curve and a change in the shape of dislocation growth centers from flat to conical. The growth kinetics of {100} faces of heterogeneous NH4Cl:Mn2+ crystals is described within the Bliznakov model using the Fowler-Guggenheim adsorption isotherm, which takes into account the lateral interaction of adsorbed particles.
