The Gibbs energy of the borates formation of trace amounts of metallic impurities (Al4B2O9, CaB2O4, CaB4O7, Ca2B2O5, Ca3B2O6, PbB2O4) in the lithium niobate charge is calculated. It is shown that the element boron, as an active complexing agent, in the composition of the B2O3 flux can prevent the transition of impurity metals, inevitably present in trace amounts in the charge of lithium niobate, into the structure of the lithium niobate crystal.

Diffraction Patterns

Using the tightly focused visible light (wavelength λ=488nm) illuminating, the ferroelectric domain patterns of the undoped lithium niobate crystal have been demonstrated. The influence of the visible light intensity on the domain nucleation field was investigated. The reduction of nucleation field decreases exponentially with increasing incident irradiation intensity. Once a domain is nucleated it can be dictated by the far-field light diffraction patterns. An assumption is proposed that the reduction of nucleation field is directly related to the defects mobility and structure of the crystals.
