Abstract
The variation in the ferroelectric transition temperature with deuteration is described by a linear function only if the deuteration level in the crystal is considered. A least‐squares fit of these data resulted in the relation Tc=121.7K + 1.07m, with m in mole% D. The effective distribution coefficient (keff) of deuterium in the system KH2PO4–KD2PO4–D2O was found to vary from 0.75 to 0.99 over the range of 25–99.8 mole% D.Keywords
