✦ Synopsis


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

Dic Beeiehung zwischen der

Deuteriumkonzentration in der Losung und der festen Phase wiihrend des Wachstums von K(H, D),PO,-Kristallen bei 30, 45 und 60 "C wurde untersucht. Die Loslichkeit von K(H, D),PO, in deuteriertem Wasser wurde gemessen. Die Konzentration von D,O in dem Losungsmittel wurde mit eincr Genauigkeit von & 0,4 molyo interferometrisch bestimmt. Die Deuteriumkonzentration in den Kristallen konnte mit einer Genauigkeit groSer als 1,2 molyo nach derselben Methode nach ihrer thermischen Zersetzung bestimmt werden. Der Deuteriumgehalt in den Kristallen ergab sich aus dem Deuteriumgehalt in der Losung. Er wird praktisch von der Temperatur nicht becinfluSt.
