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.
