Abstract

Based on the Li set vacancy model, we analyze the incorporation process of Mg ion in LiNbO₃:Mg crystals with increasing MgO doping concentration. The obtained results are in good agreement with the experimental data reported in the literature. The congruent melting compositions are predicted according to our suggested incorporation model when the (Li₂O-MgO-Nb₂O₅) system is considered as a ternary one.A procedure is suggested to find out the congruent melting compositions of LiNbO₃:Mg crystals.
