The relation between the deuterium concentration in the solution and in the solid phase during the growth of K(H, D) 2 PO 4 crystals at 30, 45, and 60°C has been examined. The solubility of K(H, D) 2 PO 4 in deuterated water was measured. The concentration of D 2 O in the solvent has been determined by means of the interferometric method with an accuracy of ± 0.4 mol%. The deuterium concentration in the crystals was measured with an accuracy better than ± 1.2 mol% by the same method after decomposing them thermally. The deuterium content in crystals is determined by the deuterium content in the solvent. It is practically not influenced by temperature.
