Abstract
The BaB2O4 crystal exhibits a high temperature-centrosymetric phase (alpha) and a low temperature-non centrosymetric phase (beta). The melting point is 1095°C and the temperature of the transition is 925°C The low temperature phase is usually grown by TSSG (Top Seeded Solution Growth) method. As Itoh et al. [1] we investigate the unusual Czochralski method which rely on the control of axial temperature gradient in a super cooled melt.
