Abstract

When grown the oxide single crystal including Li-ion, optimum oxygen condition is needed. Color and crack are caused in single crystal according too the change in the condition of the oxygen. LiTaO₃ crystals grown from off-composition of congruent melt composition under oxygen deficieny condition didn't generate any crack. LiNbO₃. LiTaO₃ crystals grown from congruent melt composition under optimum oxygen condition caused pale yellow color or colorless with no crack. Color gradually became colorless and generated cracks according to Oxygen excess.
