Abstract: A method has been developed for determining the possibility of using materials in crystallizer designs for the method of rapid growth of KDP-type crystals (dihydrogen phosphate crystals). A potassium dihydrogen phosphate crystal with dimensions of 620 $\times$ 560 $\times$ 72 mm has been obtained, grown in a crystallizer assembled on the basis of materials that had previously been tested according to the developed method.

Keywords: crystal, dihydrogen phosphate crystals, highly deuterated solutions, rapid growth, impurities, crystal growth kinetics.
