Description
Summary:At oversaturations exceeding the inert range end for face {101} due to the presence of admixture Al[(N[O.sub.3]).sub.3] x 9[H.sub.2]O, a new phase is observed during the growth of this face in the form of filamentary crystals. Some experimental dependences of the growth rate of filamentary potassium dihydrophosphate (K[H.sub.2] P[O.sub.4]) crystals on the oversaturation have been obtained at different admixture concentrations. The growth of filamentary crystals occurs by the mechanism of two-dimensional nucleation. Their formation is governed by the effect of [[AlHP[O.sub.4]].sup.+] complexes in the form of Cabrera and Vermilyea stoppers.
