摘要

Different types of defect sites generated by the impurities of divalent (M~(2+)) and trivalent (M~(3+)) metals in the structure of potassium dihydrophosphate KH_2PO_4 (KDP) were revealed by crystal-chemical analysis and computer simulation. These sites cause different deformations of the crystal matrix by generating different local strains, which enhance the inhibiting effect of impurity atoms adsorbed on the surface. This fact accounts for the different influence of di- and trivalent cations on the growth kinetics and face morphology of KDP crystals. The effect of the M~(3+) ions is associated primarily with their adsorption on the face surfaces, whereas the influence of the M~(2+) ions results from their insertion into the surface layer of the crystal.
