Abstract: | Based on the analysis of the K2O-P2O5-D2O solubility phase diagram, the optimum conditions of KD2PO4 crystallization—the compositions of mother solutions and the temperature range of crystallization—in the KH2PO4-D2O system have been determined. The technique of K(DxH1 ? x )2PO4 growth is developed. The DKDP single crystals with deuterium concentration up to 88 wt % are grown on DKDP seeds from KH2PO4 solutions in D2O by the method of temperature decrease. |
