• 要約等: Bi₄Ti₃O₁₂-PbTiO₃ micro-composite particles, Bi₄Ti₃O₁₂ core particles covered with PbTiO₃ particles with an epitaxial relationship, were synthesized. Bi₄Ti₃O₁₂ particles with a plate-like morphology were prepared by a molten salt technique and used as core particles. The Bi₄Ti₃O₁₂ particles were coated with titania by the hydrolysis of Ti-alkoxide. The thickness of the titania coating layers was easily controlled between 0.1 and 0.5μm by the concentration of Ti-alkoxide. The composite particles were prepared by the hydrothermal treatment of the titania-coated Bi₄Ti₃O₁₂ in alkali solutions containing Pb. The formation of PbTiO₃ depended both on temperature and on the concentration of Pb in the solution. The PbTiO₃ particles with the sizes of 0.1-1μm were formed on the surfaces of the Bi₄Ti₃O₁₂ core particles at temperatures≥160°C in the solutions with the excess Pb of 4-6mmol. The combined results of SEM and TEM observations revealed that there was an epitaxial relationship between Bi₄Ti₃O₁₂ and PbTiO₃ of a composite particle, such that {100} or {001} PbTiO₃//pseudotetragonal {001} Bi₄Ti₃O₁₂.
