摘要：

Supercooling behavior of BaB2O4 substituted with M (M: Al or Ga) for B was investigated. Moreover, single crystals were grown by the modified Czochralski method. Since Al and Ga are glass forming elements for the berates such as BaB2O4, large supercooling was obtained by the substitution of M for B. By controlling the M-amount single crystals of the low-temperature phase were grown, preventing glass formation. The merits of the substitution are the suppression of the solid-stale phase-transformation during growth and cooling, and the crystal hardening.
