Abstract
According to Ismailzade et al.1 LiNbO3, shows eleven anomalies in lattice parameters below the ferroelectric phase transition Tc = 1153°C. A later detected anomaly near 75°C is the most intensively investigated. An easy cracking of LiNbO3, on cooling from 80 to 60°C is reported by Xu Ziran et a1.2 Additional anomalies in birefringence,2 ultrasonic attenuation3 and Mossbauer parameters4 have been observed. Although a phase transition is suggested to occur at 75°C by some author,2, 3 the behaviour of LiNbO3 at 75°C is still not completely understood.2, 5 Encouraged by interesting results obtained in initial Mossbauer investigations of Hsia et al.4 we undertook detailed studies of the anomalies near 75 and 125°C in LiNbO3.Keywords
