A series of K(H 1− x D x ) 2 PO 4 crystals were grown from deuterated aqueous solution by using a point‐seed rapid‐growth method. The elastic, piezoelectric and dielectric constants of these crystals were determined using the resonance technique and impedance analysis, respectively. The elastic compliance constant s 11 measured in this experiment is larger than that in previous experiments, and the reliability of the results presented herein has been verified. These results show that, with increasing content of deuterium, s 11 , s 44 , s 66 , d 36 , e 36 and k 36 are gradually increased, whereas s 12 , s 13 , s 33 , d 14 , e 14 and k 14 have no demonstrable variation. The reasons for the composition dependence of these constants were analyzed based on the variation of the crystal structures resolved by single‐crystal X‐ray diffraction.
