A three-temperature-zone gradient transport technqiue has been developed for growing qualified BaTiO3 crystals. The lowest temperature zone (A zone) is the surface region, where seed is continuously lifted. The highest-temperature zone (C zone) lies on the middle of the crucible, where the temperature is the highest so as to dissolve the cyrstal embryos and clusters removed from the nutrient. The bottom of the crucible (B zone) is filled with nutrient, which is hotter than the surface region. Samples of commercial BaTiO3 photorefractive crystals are routinely grown with dimensions of approximately 30 mm×30 mm×15 mm. Lattice constants and DTA of BTO measured.
