摘要：

A model is developed for the ferroelectric-to-paraelectric phase transition in LiNbO3 and LiTaO3. The model is consistent with literature reports of nonstoichiometry, point defect formation, and phase transformation behavior. The model uses lithium Frenkel-defect-based order-disorder as the phase transformation mechanism. The phase transformation (Curie) temperature is predicted to decrease linearly with deviation from stoichiometry in agreement with experimental obsevations.
