The mechanism of the ferroelectric phase transition of CsD 2 PO 4 was investigated by examining the crystal structures determined by X-ray structure analysis at seven different temperatures above and below the transition temperature T c . The PO 4 group has two equilibrium arrangements in the paraelectric phase while only one of them remains in the ferroelectric phase. The thermal amplitude of the D atom which forms a one-dimensional chain along the ferroelectric b -axis reduces drastically at T c with decreasing temperature. These results are well described on the basis of the mechanism of the order-disorder type phase transition.
