Title: Investigation of the crystal chemical and ferroelectric properties in the vicinity of LiNbO/sub 3/ and LiTaO/sub 3/ inside the ternary systems Li/sub 2/O-Nb/sub 2/O/sub 5/-(TiO/sub 2/)/sub 2/ and Li/sub 2/O-Ta/sub 2/O/sup 5/-(SnO/sub 2/)/sub 2/

Abstract

A crystal chemical study has been carried out for the ternary systems Li/sub 2/O-M/sub 2/O/sub 5/-(M'O/sub 2/)/sub 2/ (M = Nb, M' = Ti; M = Ta, M' = Sn), in order to characterize and delimit the extension of domains of solid solutions in the vicinity of LiNbO/sub 3/ and LiTaO/sub 3/. The nature of the nonstoichiometry within these regions of solid solution has been found to be of a cationic excess or deficit. No evidence for anionic deficit has been found in this study. The ferroelectric Curie temperature T/sub C/ decreases as the composition deviates from LiNbO/sub 3/ or LiTaO/sub 3/. The decline in T/sub C/ has been interpreted on the basis of the electrostatic interactions resulting from either cationic excess or deficit.
