| Abstract: | According to the Li vacancy model of intrinsic defect in LiNbO 3 the defect structures formed in LiNbO 3: Mg with varying Mg contents are proposed. The Li 2O, Nb 2O 5 contents / ratio, in crystals and the densities of the crystals are calculated by using the defect models. The calculated values are in good agreement with the experimental results. |
