Abstract
The chemical interaction in the Li2CO3–Nb2O5 and Li2O–B2O3–Nb2O5 systems and crystallization features of LiNbO3 crystals from the melts containing boron impurity are considered. Raman spectra of LiNbO3:B crystals grown from a congruent melt containing ~0.55–1.24 mol % of B2O3 are studied. There are noticeable changes in the entire Raman spectrum upon doping with boron, which indicates a change in alternation of the main cations and vacancies along the polar axis of the LiNbO3:B crystal and “perturbation” of oxygen octahedra. Moreover, expansion of oxygen octahedra is anisotropic with an increase in boron concentration in the melt. Boron, hardly entering the structure of the lithium niobate crystal, significantly changes the structure of the melt and thus has a significant effect on structure and physical characteristics of the LiNbO3:B crystals. The results obtained for the LiNbO3:B crystals are compared with those obtained for nominally pure stoichiometric (LiNbO3stoich) and congruent (LiNbO3cong) lithium niobate crystals.
