Abstract

The growth kinetics and elementary growth processes on the surface of NHCl:Mn heterogeneous crystals formed in the NHCl-MnCl-HO-CONH system are experimentally studied. It is found that a change in the composition of complexes in an NHCl crystal from Mn(NH)Cl · 2HO to MnCl · 2CONH 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 NHCl:Mn crystals is described within the Bliznakov model using the Fowler-Guggenheim adsorption isotherm, which takes into account the lateral interaction of adsorbed particles.
