Abstract

The crystallization of KH_2-xD_xPO₄ (DKDP) crystals with different deuterium contents ranged from 0 to 99% were investigated in solution by Attenuated Total Reflectance Infrared (ATR-IR) spectroscopy. The (H₂PO₄^-)_1-x(D₂PO₄^-)_x ionic groups were characterized by the υ₁(PO₄) and υ₃(PO₄) vibrations. The intensity changes of the υ₁(PO₄) vibration peaks and the broadened width changes of the υ₃(PO₄) vibration peaks indicate that the (H₂PO₄^-)_1-x(D₂PO₄^-)_x concentration increases with the measurement time increases. Besides, the appearance of δ(P-O...H/D-O-P) vibration illustrates the formation of (H₂PO₄^-)_n-x(D₂PO₄^-)_x clusters, which can be confirmed as growth unite. The intensity changes of the H-O-H and D-O-D vibration at the wavenumbers from 1 448 cm^-1 to 1 653 cm^-1can illustrate the un-uniform distribution of deuterium contents in DKDP crystallization process.
