Flux growth of bulky hexagonal BaTiO₃ single crystal.

抄録

Bulky single crystals of hexagonal BaTiO₃ were grown by the flux method using KF and K₂CO₃ without quenching. The crystals of amber color have a hexagonal dipyramid-like habit belonging to the holohedral class D_6h–6⁄mmm with their lattice parameters a=5.722±0.002 and c=14.049±0.003 Å and with the space group P6₃⁄mmc. K₂CO₃ is very effective to grow the bulky BaTiO₃ single crystals.
