The BaTi₂O₅–Ba₆Ti₁₇O₄₀ eutectic (BaO–68.7 mol% TiO₂) was directionally solidified by the floating zone (FZ) method and crystalline phases, microstructures and orientation were investigated. Ba₆Ti₁₇O₄₀ with faceted rod-like shape was dispersed in the BaTi₂O₅ matrix. The growth directions of BaTi₂O₅ and Ba₆Ti₁₇O₄₀ were parallel to the b and a axis, respectively, and the orientation relations were BaTi₂O₅ (010)//Ba₆Ti₁₇O₄₀ (602̅) and BaTi₂O₅ (001)//Ba₆Ti₁₇O₄₀ (001).
