文摘

In this work, we have investigated experimentally and theoretically, the evolution of a density of solid solutions synthetised in the vicinity of LiTaO₃ in the ternary system Li₂O–Ta₂O₅–(CuO)₂ with a rate of % Cu and by two modes of cooling (slow and rapid cooling), for different solid solutions synthetised. We have realized that the mechanisms of non-stoichiometry for different phases at Cu2+ are sensitive to the cooling modes. In order to study by our theoretical approach, the correlation of the evolutions of density with defects structure of Cu-doped LiTaO₃, we have proposed vacancy models that can explain the mechanism of substitution. The correlation of the density evolution with defects structure of Cu-doped LiTaO₃, is investigated by using the theoretical approach which combined with proposed vacancy models in order to explain the substitution mechanism. The analytical modeling reproduce experimental measurements specifying the nature of substitution required.
