Abstract

Perovskite-type NaTaO₃ is best known as a semiconductor photocatalyst that splits water under ultraviolet (UV) light irradiation. Here, we report the flux growth of millimeter-sized, platy NaTaO₃ crystals using Na₂MoO₄ as the flux. During flux growth, the crystal size and the number of anisotropic crystals increased as the holding temperature was increased from 1100 to 1500 °C. By slowly cooling from 1500 to 1300 °C at a rate of 5 °C·h^-1, rectangular platy crystals grew up to 8.0 mm × 4.7 mm × 0.044 mm. The grown NaTaO₃ crystals belonged to orthorhombic system and the index of the well-developed faces was {010}.
