摘要：

Czochralski growth of PrGaO3 single crystal is investigated. A multitude of twins and fine cracks are still included in the crystal boules, but crystals less than 5 mm in diameter are almost entirely crack- and twin-free. To clear up the occurrence of twins, high temperature measurements (high temperature X-ray diffractometry and thermal analysis) were performed. The results suggest the existence of a phase transition, presumably orthorhombic-rhombohedral transition, above 1400-degrees-C. This high temperature transition causes twins.
